Participants

Reaction Steps

Raney® nickel (293 mg, 1.71 mmol) was added to a solution of (R)—N-(1-(4-chlorophenyl)ethyl)-4-cyano-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (Intermediate 45) (466 mg, 1.14 mmol), in ethanol (30 mL). Ammonium hydroxide (10 mL) was added. This mixture was first purged with nitrogen, then placed under a balloon of hydrogen and stirred for 36 hours. The reaction mixture was filtered through celite and the solvent evaporated to dryness. The crude product was purified by flash silica chromatography, elution gradient 0 to 10% 7N ammonia/MeOH in DCM. Pure fractions were evaporated to dryness to afford (R)-4-(aminomethyl)-N-(1-(4-chlorophenyl)ethyl)-1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperidine-4-carboxamide (276 mg, 58.6%) as a white solid.
