Procedure
A stirred solution of 7-methylthio-4-oxo-2-(2-propoxyphenyl)-3,4-dihydropyrimido[4,5-d]pyrimidine (0.60 g) and morpholine (1.25 g) in pyridine (20 ml) was heated under reflux for 45 hours. The reaction mixture was evaporated under reduced pressure to yield a crude product which was washed with water and twice recrystallised from methanol to yield the title compound, 0.25 g, m.p. 175.5°-177° C.
