    • 2O for 5 min gave 80% of 5,7-dimethyl-1,8-naphthyridin-4-one. When we repeated the experiment 6,8-dimethyl-4 H -pyrido[1,2-a ]pyrimidin-4-one was the main product, in agreement with the result of Lesher. (13) After a reaction of time 5 h, the amounts of pyridopyrimidinone and 1,8-naphthyridinone were nearly equal
