Procedure

A stirred mixture of 5,6-dihydro-3-methylthio-5-oxo-7-(2-propoxyphenyl)pyrimido[5,4-e][1,2,4]triazine (0.80 g) and sodium methoxide (prepared from sodium, 0.28 g and methanol) in methanol (50 ml) was heated under reflux for 1.5 hours. The cooled reaction mixture was neutralised by the addition of glacial acetic acid (0.7 ml) to afford a yellow precipitate (0.63 g) which was recrystallised from methanol to afford the title compound, 0.47 g, m.p. 221-°222° C.
