Procedure

To a solution of 92% pure N1-{4-[4-amino-7-(4-oxocyclohexyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl]-2-methoxyphenyl}-3-phenylpropanamide (1.0 g, 2.1 mmol), N-methylpiperazine (0.63 g, 6.3 mmol), acetic acid (0.38 g, 6.3 mmol) in dichloroethane (100 mL) was added sodium triacetoxyborohydride (0.67 g, 3.15 mmol) portionwise under nitrogen. The solution was stirred for 20 hr and then quenched by the addition of saturated aqueous sodium bicarbonate solution (50 mL). The aqueous layer was extracted with dichloromethane (3×50 mL), dried (sodium sulphate), filtered and evaporated to leave a sludge which was purified by flash silica gel column chromatography using dichloromethane to 50% MeOH/dichloromethane in 10% increments. F84-96 were combined and evaporated to leave cis-N1-(4-{4-amino-7-[4-(4-methylpiperazino)cyclohexyl]-7H-pyrrolo[2,3-d]pyrimidin-5-yl}-2-methoxyphenyl)-3-phenylpropanamide (0.26 g) as a cream foamy glass.

F121-138 were combined and evaporated to leave trans-N1-(4-{4-amino-7-[4-(4-methylpiperazino)cyclohexyl]-7H-pyrrolo[2,3-d]pyrimidin-5-yl}-2-methoxyphenyl)-3-phenylpropanamide (0.11 g) as a white solid.
