Reaction Steps

100 mg of 6-chloro-N-(3-methoxyphenyl)pyrimidin-4-amine, 27 mg of ethanolamine and 119 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 off and to the evaporation residue obtained 5 mL of water were added. The mixture obtained was extracted with EtOAc, the phases were separated and the organic phase obtained was dried and subjected to evaporation. 2-(6-(3-Methoxyphenylamino)pyrimidin-4-ylamino)ethan-1-ol was obtained in the form of a yellow oil.
