Reaction Steps

A solution of 6-[2-(dimethylamino)-1-azavinyl]-1-ethyl-3-propyl-1,3-dihydropyrimidine-2,4-dione (2.1 g) was dissolved in a mixture of methanol (10 ml) and 28% aqueous ammonia solution (20 ml), and stirred for 72 hours at room temperature. Solvent was then removed under reduced pressure, and the residue purified by chromatography on a silica gel column, eluting with a mixture of dichloromethane/methanol (15/1), to provide 6-amino-1-ethyl-3-propyl-1,3-dihydropyrimidine-2,4-dione, a compound of formula (8).
