YieldReaction ConditionsOperation in experiment
74% General procedure: The Vilsmeier-Haack reagent was prepared by adding POCl3 (60 mmol, 6 mL) dropwise to ice-cold dry DMF (30 mL) whilst stirring. The mixture was then stirred for 10-15 min at 0 C. Compound 3b or 3e (10 mmol) was added as a solution in DMF (5 mL) to the above Vilsmeier-Haack reagent. The stirred mixture was then heated at 35 C for 1 h. After cooling, ice water (6 mL) and a 30% aqueous solution of NaOH (13 mL) were added successively, and the mixture was heated at reflux for 20 min and allowed to cool. The mixture was extracted with CH2Cl2 (20 mL*3). The extracts were dried over Na2SO4, evaporated under reduced pressure to remove the solvent, and the crude product was purified by flash column chromatography using 15-25% acetone/petroleum ether (60-90 C) as eluent to give the corresponding intermediate compound 4b or 4e, respectively.
With trichlorophosphate; at 0 - 20℃;Inert atmosphere; Procedure for Vilsmeiere-Haack reaction followed by LiAlH4 reduction was adapted from Petit et al.16 In a flame-dried flask under nitrogen, POCl3 (0.42 mL, 4.6 mmol) was added at 0 C to 4-methyl-1H-indole (0.5 g, 3.8 mmol) in DMF (7.6 mL). The reaction was stirred at room temperature overnight. 2 N NaOH(aq) was then added, the solution was stirred for 2 h, then poured into EtOAc. The organic layer was washed with brine, dried (Na2SO4), filtered, and concentrated. The crude aldehyde was carried forward without further purification.

A 5N aqueous solution of sodium hydroxide (15 ml) was added thereto, followed by stirring at 100 C. for further 30 minutes. The reaction solution was cooled, and the precipitated crystals were collected by filtration to give 4-methylindole-3-carboxaldehyde (Compound III-1, 1.14 g). 1 H-NMR (90 MHz, CDCl3) delta2.83 (s, 3H), 6.98-7.29 (m, 3H), 7.89 (d, J=3.0 Hz, 1H), 9.11 (brs, 1H), 10.10 (s, 1H) EI-MS m/z=159 (M+)

79% General procedure: NaH (60% dispersion in mineral oil, 20.00 mmol, 0.48 g) wasa dded portionwise to a stirred solution of the aldehyde 4 (10.00 mmol) in anhydrous THF (25 mL) cooled in an ice bath. The resulting mixture was then slowly allowed to warm to r.t. After stirring for 30 min, PhSO2Cl (12.00 mmol) (CH3COCl 12.00 mmol for5f) in anhydrous THF (5 mL) was added dropwise. When TLC monitoring showed that the starting material 4 had disappeared, the reaction mixture was evaporated under reduced pressure to remove the solvent and was then diluted with ice water (50 mL). Solid products were filtered off and recrystallized from acetone/petroleum ether (60-90 C) to give the desired intermediate 5.

43% With lithium aluminium tetrahydride; In tetrahydrofuran; for 8.5h;Reflux; A solution of <strong>[4771-48-6]4-methyl-1H-indole-3-carbaldehyde</strong> (2.200 g, 13.82 mmol) in THF (50 mL) was added to a refluxing mixture of lithium aluminum hydride (1.154 g, 30.4 mmol) in THF (50 mL) (reflux condenser fitted to a two neck flask) over 30 min. The reaction mixture was refluxed for 8 hours, cooled to room temperature and treated with diethyl ether (~50 mL). The reaction mixture was acidified to ~pH 3 with 1N HCl, while cooling in an ice bath. The reaction mixture was diluted with EtOAc (125 mL), poured into a separatory funnel and washed with water (2X 50 mL), saturated aqueous NaCl solution (50 mL), then dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated in vacuo to afford 3,4-dimethyl-1H-indole (0.870 g, 5.99 mmol, 43% yield). LC retention time 1.15 min [Method F1]. MS (E-) m/z: 146.0 (M-H).
With lithium aluminium tetrahydride; In tetrahydrofuran; for 4h;Inert atmosphere; Reflux; In a flame-dried flask under nitrogen, a solution of the Vilsmeiere-Haack product (0.39 g, 2.5 mmol) in THF (5 mL) was added dropwise to a suspension of LiAlH4 (0.19 g, 5 mmol) in THF (1.6 mL). The reaction was heated to reflux for 4 h, then cooled to room temperature and stirred overnight. The reaction was diluted with Et2O and cooled to 0 C. Water (0.19 mL) was added slowly, then 15% NaOH(aq) (0.19 mL), then water (0.6 mL) were added. The mixture was warmed to room temperature and stirred for 15 min. Some MgSO4 was added, the mixture was stirred for 15 min, filtered, and concentrated. The crude indole was carried forward without further purification.
With lithium aluminium tetrahydride; In tetrahydrofuran; at 20℃; for 8h;Cooling with ice; Green chemistry; General procedure: This method is a general method. To a dry flask, LiAlH4 (15.0 mmol) was added, and TauHF (30.0 mL) was used as a solvent. The above-mentioned crude indole-3-formaldehyde THF (30.0 mL) solution was added dropwise under ice-water bath, and the mixture was allowed to react to room temperature for about 8 hours. The reaction was completely monitored by TLC. To the flask was added 1.0 mL of ice water, and then 1.5 g of NaOH solid and 3.0 mL of water were slowly added. After the reaction was completed, the mixture was stirred at room temperature for about 15 minutes, then the solid was filtered, and the filtrate was extracted with ethyl acetate. (3X 20.0 mL).
