To a stirred solution of N,N-dicyclopropyl-6-ethyl-4-(5-formyl-1-methyl-1H-pyrazol-3-ylamino)-1-methyl-1,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridine-7-carboxamide (example 112B, 22 mg, 0.049 mmol) and molecular seives 4 Å (30 mg) in MeOH (2 mL) was added morpholine (0.017 mL, 0.197 mmol). After the solution was stirred at room temperature for 12 hrs, sodium borohydride (7.46 mg, 0.197 mmol) was then added and stirred for 3 hrs. The solution was brought to pH=4 with 1N HCl, neutralized with saturated aqueous sodium bicarbonate, and then extracted with CH2Cl2. The organic layer was dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was purified by silica-gel flash chromatography using an Isco 40 g column eluting from 0-10% MeOH/CH2Cl2 to yield N,N-dicyclopropyl-6-ethyl-1-methyl-4-(1-methyl-5-(morpholinomethyl)-1H-pyrazol-3-ylamino)-1,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridine-7-carboxamide (14.3 mg, 0.027 mmol, 54.9% yield) as a white solid.
