YieldReaction ConditionsOperation in experiment
76% With diisobutylaluminium hydride; In tetrahydrofuran; toluene; at -78 - 20℃; for 1h;Inert atmosphere; A solution of Intermediate 312B (410 mg, 2.263 mmol) in Toluene (11.500 mL) and THF (11.50 mL) was cooled to -78 C under an atmosphere of N2. DIBAL-H (1.0 Min Toluene) (3.40 mL, 3.40 mmol) was then added to the cooled solution dropwise. After the initial bubbling had subsided, the reaction mixture was allowed to thaw to room temperature. After 1 h, the reaction mixture was cooled to 0 C and quenched with 1.0 M HC1. The resulting suspension was stirred vigorously for 45 mm to fully cleave the aluminate complex. The mixture was then diluted with EtOAc and extracted. Theorganic phase was washed with brine, dried over MgSO4, filtered and concentrated. The resulting crude product was purified by ISCO (80g, 0-100% EtOAc/Hexanes, 33 mm. Product at 50%) to give Intermediate 312C (370 mg, 1.717 mmol, 76% yield) as a light yellow solid. LC-MS.

YieldReaction ConditionsOperation in experiment
With triphenylphosphine; In carbon tetrabromide; acetonitrile; 13.9 g of carbon tetrabromide and then 8.9 g of triphenylphosphine are added in the course of 10 min to a solution of 5.2 g of <strong>[5804-49-9]2-methoxy-5-nitrophenylmethanol</strong> in 150 cm3 of acetonitrile. The mixture is stirred for 1 hour at a temperature close to 20 C. and then concentrated to dryness under reduced pressure (2.7 kPa) at 40 C. The crude product obtained is purified by chromatography on 25 g of silica (0.065-0.200 mm) contained in a column 4.0 cm in diameter [eluent: methylene chloride/petroleum ether (40/60 by volume)], collecting 125 cm3 fractions. Fractions 5 to 12 are combined and concentrated to dryness under reduced pressure (2.7 kPa) at 40 C. 5.6 g of 2-methoxy-5-nitrobenzyl bromide melting at 78 C. are thus obtained.

87% General procedure: IF2a To a mixture of carboxylic acid IF1a (1.81 g, 10.0 mmol) and N-methylmorpholine (1.11 g, 11.0 mmol) in THF (20 mL) at 0 C. was added ethyl chloroformate (1.19 g, 11.0 mmol). The mixture was allowed to stir at 0 C. for an additional 30 min and filtered. The insoluble salt was washed with THF (5 mL*3). To the filtrate was added NaBH4 (1.13 g, 30 mmol) and the resulting mixture was then stirred at rt for 2 h. The reaction mixture was quenched with saturated NH4Cl (50 mL) and extracted with EtOAc. The organic phase was washed with water and brine, dried over anhydrous K2CO3, and concentrated in vacuo. The residue was purified by flash column chromatography (EtOAc/hexanes) to afford compound IF2a as a colorless oil (1.60 g, 94%). 1H NMR (CDCl3, 600 MHz) delta 8.31 (d, J=2.4 Hz, 1H), 8.06 (dd, J=8.1, 2.7 Hz, 1H), 7.32 (d, J=9.0 Hz, 1H), 4.79 (d, J=4.8 Hz, 2H), 1.57 (s, 3H).

palladium; The crude product obtained is purified by chromatography on 50 g of silica (0.065-0.20 mm) contained in a column 3 cm in diameter [eluent: methylene chloride/ethanol (95/5 by volume)], collecting 20 cm3 fractions. Fractions 21 to 29 are combined and concentrated to dryness under reduced pressure (2.7 kPa) at 40 C. After recrystallization from acetonitrile, 0.82 g of 2-{2-[3-(3-hydroxymethyl-4-methoxyphenyl)ureido]-N-phenylacetamido}-N-methyl-N-phenylacetamide melting at 181 C is thus obtained. 5-Amino-2-methoxyphenylmethanol may be prepared in a manner analogous to that described in Example 99 for the preparation of methyl (RS)-3-aminomandelate, but using 3 g of <strong>[5804-49-9]2-methoxy-5-nitrophenylmethanol</strong> and 0.5 g of 5% palladium-on-charcoal as the starting material. 1.2 g of 5-amino-2-methoxyphenylmethanol are thus obtained in the form of a meringue which is used as such in the subsequent syntheses. 2-Methoxy-5-nitrophenylmethanol may be prepared in the following way:
