Reaction Steps

To a solution of 2-(4-methoxyphenyl)ethanol (183 mg, 1.202 mmol) and 8-chloro-1-methyl-3,4-dihydro-1H-pyrimido[1,6-a]pyrimidin-6(2H)-one (200 mg, 1.002 mmol) in dimethyl sulfoxide (DMSO) (5 mL) stirred at room temp was added NaH (100 mg, 2.505 mmol) portionwise. The reaction mixture was stirred at room temp for 2 hr. The reaction was quenched with water and purified by prep-HPLC to give the title product as a white solid (150 mg).
