Reaction Steps

A mixture of 2,5-dichloro-N-(5-methyl-1H-pyrazol-3-yl)pyrimidin-4-amine (120 mg, 0.49 mmol) and 2,5-dimethyl-4-(piperidin-2-yl)aniline (100 mg, 0.49 mmol) in 2-propanol (10 mL) was treated with conc. aqueous HCl (7 drops). The mixture was sealed and heated in a microwave at 130° C. for 45 min. The mixture was concentrated to afford 5-Chloro-N2-(2,5-dimethyl-4-(piperidin-2-yl)phenyl)-N4-(5-methyl-1H-pyrazol-3-yl)pyrimidine-2,4-diamine; ESMS m/z 412.1 (M+H+). The crude product was used directly for the next step without further purification.
