Reaction Steps

A solution of 6-(4-acetylthiosemicarbazido)-1-benzyl-3-propylpyrimidine-2,4(1H,3H)-dione (3.0 g) in dimethylformamide (50 ml) was heated at 100° to 110° C. for 60 hours. The reaction mixture was concentrated and dissolved in 90% methanol. The solution was left standing for cooling to give pale brown crystals, followed by recrystallization from ethanol to obtain colorless crystals, m.p. 108° to 110° C.
