Participants

Reaction Steps

Trifluoroacetic acid (0.1 μL, 1.298 μmol) was added to tert-butyl 4-(2-(5-cyanopyrazin-2-ylamino)-5-(4-methoxyphenyl)pyridin-4-ylamino)piperidine-1-carboxylate (4 mg, 7.97 μmol) dissolved in dichloromethane (0.45 mL) and the mixture was stirred for 1 hr. The mixture was concentrated and purified by ion exchange on (solute SCX II acidic resin (1 g), eluting with MeOH then 2M NH3-MeOH. The basic fractions were combined and concentrated. Preparative thin layer chromatography, eluting with 10% MeOH/1% NH3/89% dichloromethane) gave 5-(5-(4-methoxyphenyl)-4-(piperidin-4-ylamino)pyridin-2-ylamino)pyrazine-2-carbonitrile (2 mg, 4.98 μmol, 62.5% yield) as a yellow powder.
