Versuchsvorschrift

A representative synthesis of benzylidene adduct is given. Compound A (1.51 g, 8.37 mmol) was dissolved in a mixture of methanol (35 ml) and acetic acid (5 ml) in a 50 ml boiling flask on a steam bath. To this was added a methanolic solution (60 ml) of freshly synthesized 5,6-diamino-1,3-dipropyluracil. After heating 15 minutes, the volume was reduced by evaporation until crystallization occurred. Ether (40 ml) was added and the nearly white solid was collected. Yield 2.80 g (86%), mp 179°-180° C. Analysis (C19H24N4O5): calc. 58.60% C, 6.21% H, 14.39% N; found 58.72% C, 6.16% H, 14.43% N.
