Reaction Steps
A mixture of α-cyano-β-ethoxy-N-ethoxycarbonylacrylamide (0.047 mol), 3,4-dichloroaniline (8.15 g) and ethanol (70 ml) is heated to prepare α-cyano-β-(3,4-dichloroanilino)-N-ethoxycarbonylacrylamide, which is cyclized by heating overnight in tetralin to yield 5-cyano-1-(3,4-dichlorophenyl)uracil, m.p. 206.5°-207.5°.
