Reaction Steps

250 mg of 6-chloro-N-(4-methoxyphenyl)pyrimidine-4-amine in the form of a hydrochloride, 62 mg of ethanolamine and 296 mg of DIPEA were dissolved in 2 mL of n-BuOH and the mixture obtained was charged into a microwave vial and the vial obtained was heated to 200° C. for 45 minutes under microwave irradiation. Progress of the reaction was monitored by TLC. Upon termination of the reaction n-BuOH was evaporated. The evaporation residue was subjected to crystallization from an n-BuOH/EtOH solvent mixture.
