Reaction Steps

To a solution of tert-butyl 4-(6-(5-chloro-4-(5-methyl-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-3-ylamino)pyrimidin-2-ylamino)-4-methylpyridin-3-yl)piperidine-1-carboxylate in DCM (1 mL), was added TFA (1 mL). The mixture was stirred for 1 h and concentrated to afford 5-chloro-N4-(5-methyl-1H-pyrazol-3-yl)-N2-(4-methyl-5-(piperidin-4-yl)pyridin-2-yl)pyrimidine-2,4-diamine as brownish oil. The product was used directly for subsequent reactions without further purification.
