Reaction Steps

A stirred mixture of 3-methylthio-8-oxo-6-(2-propoxyphenyl)-7,8-dihydropyrimido[4,5-e][1,2,4]triazine (0.5 g) and sodium methoxide (prepared from sodium, 0.17 g, and methanol) in methanol (50 ml) was heated under reflux for 3 hours. The cooled reaction mixture was evaporated under reduced pressure to afford a yellow solid which was dissolved in water and acidified with 2 Normal hydrochloric acid to yield a yellow solid (420 mg) which was recrystallised from dimethylformamide to afford the title compound, 0.16 g, m.p. 298°-299° C.
