Procedure

Crude tert-butyl 3-((2-(5-cyanopyrazin-2-ylamino)-5-(3-(morpholinomethyl)-1H-pyrrol-1-yl)pyridin-4-ylamino)methyl)piperidine-1-carboxylate (90 mg) was dissolved in methanol (1 mL) and absorbed onto a TsOH solid phase extraction cartridge and allowed to stand for 2 h. The cartridge was eluted with 7M ammonia in methanol. The basic fractions were evaporated to dryness. The crude product was purified by HPLC to give 5-(5-(3-(morpholinomethyl)-1H-pyrrol-1-yl)-4-(piperidin-3-ylmethylamino)pyridin-2-ylamino)pyrazine-2-carbonitrile (4.93 mg, 7% over 3 steps).
