Versuchsvorschrift

A mixture of 2,5-dichloro-N-(5-methyl-1H-pyrazol-3-yl)pyrimidin-4-amine (Intermediate 1, 132 mg, 0.54 mmol) and tert-butyl 4-(4-amino-5-fluoro-2-methylphenyl)piperidine-1-carboxylate (Intermediate 19, 166 mg, 0.54 mmol) in 2-propanol (15 mL) was treated with conc. aqueous HCl (14 drops). The mixture was sealed and heated in a microwave at 130° C. for 60 min. The mixture was concentrated to afford 5-chloro-N2-(2-fluoro-5-methyl-4-(piperidin-4-yl)phenyl)-N4-(5-methyl-1H-pyrazol-3-yl)pyrimidine-2,4-diamine as a yellow solid. A portion of the crude product was purified with preparative RP-HPLC to afford 5-chloro-N2-(2-fluoro-5-methyl-4-(piperidin-4-yl)phenyl)-N4-(5-methyl-1H-pyrazol-3-yl)pyrimidine-2,4-diamine as a white solid; ESMS m/z 416.1 (M+H+). The remainder of the crude product was used directly for the next step without further purification.
