実験手順
In a manner similar to that described for the preparation of 3-(1H-tetrazol-5-yl)-4H-pyrido[1,2-a]pyrimidin-4-one in Example 2, the title compound was prepared from ethyl 2-cyano-3-(5-methyl-2-pyridylamino)acrylate. The product (42.8% yield) had m.p. 321°-322° (decomp) after recrystallization from glacial acetic acid.
