Reaction Steps

Sodium boronhydride (10 wt % on alumina, 13.14 mg, 0.035 mmol) was added to N,N-dicyclopropyl-6-ethyl-4-(1-ethyl-5-formyl-1H-pyrazol-3-ylamino)-1-methyl-1,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridine-7-carboxamide (example 101C, 16 mg, 0.035 mmol) in methanol (1 mL) at room temperature and the reaction mixture stirred for 0.5 h. The solid alumina was filtered off and the filtrate was concentrated in vacuo. The crude product was purified by flash chromatography on silica gel using an automated ISCO system (4 g column, eluting with 2-10% methanol/dichloromethane). N,N-dicyclopropyl-6-ethyl-4-(1-ethyl-5-(hydroxymethyl)-1H-pyrazol-3-ylamino)-1-methyl-1,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridine-7-carboxamide (14 mg, 86% yield) was obtained as a white solid.
