A solution of tert-butyl 4-((2-(5-cyanopyrazin-2-ylamino)-5-(2-(dimethylamino)acetamido)pyridin-4-yloxy)methyl)piperidine-1-carboxylate (24 mg, 0.047 mmol) and trifluoroacetic acid (2 mL) in dichloromethane (10 mL) was stirred for 45 minutes. The solution was concentrated and the residue was loaded onto a MP-TsOH SPE cartridge. Elution with 2M ammonia in methanol gave N-(6-(5-cyanopyrazin-2-ylamino)-4-(piperidin-4-ylmethoxy)pyridin-3-yl)-2-(dimethylamino)acetamide as a yellow solid (14 mg, 72%).
