Procedure
5,6-Dihydro-3-methylthio-5-oxo-7-(2-propoxyphenyl)pyrimido[5,4-e][1,2,4]triazine (0.7 g) was heated for 30 hours with ethanolic ammonia (50 ml) at 100° C. in a pressure vessel. The cooled mixture was filtered to give the crude product (0.21 g) which was recrystallized from ethanol to give the pure title compound, m.p. 322-325° C.
