A solution of (E)-tert-butyl 4-((2-(5-cyanopyrazin-2-ylamino)-5-(3-methoxyprop-1-enyl)pyridin-4-ylamino)methyl)piperidine-1-carboxylate (Synthesis 183-B) (0.035 g, 0.073 mmol), palladium on carbon (0.035 g) in methanol (2 mL) was stirred overnight under hydrogen (1 atm). The reaction mixture was filtered through celite and the solvent was removed in vacuo. The crude product was used without further purification. TFA (0.2 mL) was added to a solution of the crude material dissolved in dichloromethane (2 mL) at room temperature. The reaction mixture was stirred for 20 min. Solvent was removed in vacuo and the mixture was purified by ion exchange on SCX-II acidic resin (500 mg) eluting with methanol, then 2M ammonia-methanol. The basic fractions were combined and the solvent was removed in vacuo. The crude product was purified by preparative thin layer chromatography, eluting with methanol/dichloromethan/NH3 (9%/90%/1%), to give the title compound as a yellow solid (0.020 g, 84%).
