Procedure
To a warm solution of α-cyano-β-ethoxy-N-ethoxycarbonylacrylamide (14.8 g) and ethanol is added p-chloroaniline (8.9 g) in ethanol. Precipitate appears instantaneously. The mixture is stirred at room temperature for one hour and filtered to yield α-cyano-β-(4-chloroanilino)-N-ethoxycarbonylacrylamide, m.p. 177°-183°.
