Procedure
Thionyl chloride (112 mL, 1.54 mmol) was added to a solution of 3-(2-hydroxyethyl)-8-mesityl-2,6-dimethylimidazo[1,5-a]pyrimidin-4-ol (500 mg, 1.54 mmol) in toluene (5 mL) at 80° C., followed by stirring for one hour. After cooling to room temperature, the resulting crystals were washed with diethyl ether, to give the title compound (360 mg) as pale brown crystals.
