Procedure

To a solution of 7-cyclopentyl-2-(5-piperazin-1-yl-pyridin-2-ylamino)-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid dimethylamide (30 mg, 0.069 mmol) in 10 mL of dichloromethane is added 1 mL of acetone and NaB(OAc)3H (30 mg, 0.138 mmol). The resulting mixture is stirred at room temperature for 18 h. Following purification by preparative LCMS gave 7-cyclopentyl-2-[5-(4-isopropyl-piperazin-1-yl)-pyridin-2-ylamino]-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid dimethylamide (20 mg, 61%). MS(ESI) m/z 477.3 (M+H)+
