Reaction Conditions

Reaction Steps

To a solution of 4-n-propyl-imidazo[1,5-d]-as-triazin-1(2H)-one (0.01 mol) in dimethylformamide (50 ml) is added sodium methoxide (0.01 mol) followed by the addition of allyl bromide (0.012 mol). The reaction mixture is stirred at 20° C. for 16 hours, then heated at 40° C. for 45 minutes, cooled and poured on a mixture of ice and dilute hydrochloric acid. The product is isolated by extraction with chloroform and evaporation. It is purified by recrystallization from cyclohexane or a cyclohexane-benzene mixture; or by silica gel dry column chromatography in chloroform.
