Reaction Steps
A mixture of 2.3 g of 3- (1H-tetrazol-5-yl) -6-methyl-4-oxo-4H-pyrido[1,2-a]pyrimidine, 50 ml of dimethylformamide, 1.38 g (0.001 mole) of anhydrous potassium carbonate and 2.85 g (0.02 moles) of methyl iodide was stirred at 80° C. for 1 hour. The reaction mixture was cooled to room temperature and diluted with 150 ml of water. The precipitating crystals were collected. 1.61 g (66.53%) of the title compound was obtained, which was crystallized from dimethylformamide, m.p.: 232°-234° C.
