Step A: Phenyl(1H-pyrrolo[2,3-b]pyridin-6-yl)methanone In a round-bottomed flask under argon, 25.2 ml of 1M phenylmagnesium bromide in tetrahydrofuran are dissolved in 7 ml of anhydrous tetrahydrofuran. In another round-bottomed flask under argon, 0.6 g of <strong>[189882-33-5]1H-pyrrolo[2,3-b]pyridine-6-carbonitrile</strong> and 1.07 ml of trimethylsilyl chloride are dissolved in 7 ml of tetrahydrofuran. That solution is then pipetted onto the magnesium solution at ambient temperature. After stirring for one night, the mixture is hydrolyzed with 20 ml of 2N ammonium chloride solution. The pH is then adjusted to 1 using 10% hydrochloric acid and the solution obtained is stirred for 2 hours at ambient temperature. The pH of the solution is adjusted to 9 using concentrated ammonium hydroxide solution and the aqueous phase is extracted twice with 20 ml of dichloromethane. The organic phases are dried over magnesium sulphate, filtered and evaporated under reduced pressure. After purification by chromatography on silica gel (pure dichloromethane and then dichloromethane/methanol:99/1), the title compound is obtained in the form of a yellow solid. Melting point: 174 C.

To a solution of lH-Pyitauolo[2,3-b]pyridine-6-carbonitrile (500 mg, 3.49 mmol) in THF (80 mL) was added Titanium (IV) isopropoxide (2.05 mL, 6.98 mmol) followed by EtMgBr (4.66 mL, 13.97 mmol) dropwise. The mixture was stirred at room temperature for 3 h. The dark color reaction mixture was quenched with 10 mL of H2O and stirred efficiently for 30 min. The resulting yellow suspension was filtered through a plug of celite, washed the celite cake with EtOAc followed by 10% MeOH/CH2Cl2. Solvents were removed and the resulting brown oil was suspended in Toluene (2x10 mL) to removed residual water. After evaporation of the solvent the crude amine products were obtained as a brownish solid. To a mixture of these crude amines and DIEA (801 uL, 4.60 mmol) in DCM (15 mL) was added BoC2O (810 mg, 3.71 mmol). The mixture was stirred at room temperature for 16 h. The reaction was diluted with DCM and washed with water, followed by Brine. Dried over MgSO4, filtered and concentrated down to provide crude material which was purified by silica gel chromatography (5% to 50% EtOAc in hexane) to give 80 mg of [1-(lH-Pyrrolo[2,3-&]pyridin-6-yl)-cyclopropyl]- carbamic acid tert-butyl ester (m/z 274.40 [M + I]+) and 230 mg of [1-(1H-Pyrrolo[2,3- b]pyridin-6-yl)-propyl]-carbamic acid tert-butyl ester m/z 276.41 [M + I]+

67 mg With potassium carbonate; In N,N-dimethyl-formamide; at 20℃; for 3h; To a solution of the compound [96-2] obtained in the process (2) (40 mg) in N,N-dimethylformamide (2 mL) were added potassium carbonate (82 mg) and 2,6-dimethylbenzyl chloride (69 mg) at room temperature, and then the reaction mixture was stirred at room temperature for 3 hours. The reaction mixture was quenched with water, and extracted with chloroform. The obtained organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give the titled compound (67 mg) as a white solid. 1H-NMR (400 MHz, CDCl3) delta: 7.98 (1H, d, J = 7.8 Hz), 7.49 (1H, d, J = 8.1 Hz), 7.22 (1H, dd, J = 8.2, 7.0 Hz), 7.12 (2H, d, J = 7.6 Hz), 6.96 (1H, d, J = 3.4 Hz), 6.46 (1H, d, J = 3.7 Hz), 5.49 (2H, s), 2.27 (6H, s).

50% To a mixture of AICI3 (2.2 g, 16.8 mmol) in anhydrous DCM (50 mL) at 0C was added acetyl chloride (2.1 g, 33.5 mmol). The mixture was stirred at r.t. for 1 hr, followed by addition of a solution of lH-pyrrolo[2,3-b]pyridine-6- carbonitrile (800 mg, 5.6 mmol) in anhydrous DCM (20 mL). The resulting mixture was stirred at r.t. for 2 hr then poured into ice -water and extracted with DCM. The combined organic layers were washed with brine, dried over anhydrous Na2SC>4, and concentrated under reduced pressure. The residue was purified by flash column chromatography to afford the desired product (500 mg, 50% yield). LC-MS: m/z 186 (M+H)+.
