Reaction Steps
1-(Chloromethyl)-4-methoxybenzene (3.10 ml, 22.9 mmol) was added to a stirred solution of 9-bromopyrido[3,2-e][1,2,4]triazolo[1,5-c]pyrimidin-5(6H)-one (3.02 g, 11.35 mmol) and potassium carbonate (4.71 g, 34.1 mmol) in 1-methylpyrrolidinone (60 ml) and the mixture was heated at 40° C. for 14 hours. The mixture was filtered, and the resulting solid was washed liberally with dichloromethane. The combined organics were concentrated under vacuum and the residue was triturated with ethyl acetate (40 mL) to afford 3.07 g (70%) of the benzylated product as a brown powder.
