Reaction Steps

225 mg of 6-chloro-N-(4-phenoxyphenyl)pyrimidin-4-amine, 82 mg of ethanolamine and 173 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 60 minutes under microwave irradiation. Progress of the reaction was monitored by TLC. Upon termination of the reaction n-BuOH was evaporated and the evaporation residue was subjected to MPLC purification (EtOAc:EtOH=10:1). 2-(6-(4-Phenoxyphenylamino)pyrimidin-4-ylamino)ethan-1-ol was obtained in the form of a colorless solid.
