Procedure

A mixture of 50 g. (0.2 m.) of the above-prepared rhodanine and 140 g. (0.86 m.) of triethylorthoacetate in 350 ml. of acetic anhydride is refluxed for four hours. The cooled reaction solution is filtered and the product is washed with 100 ml. of 70% aqueous acetic acid to yield 3-(4'-chlorophenyl)-5-(1'-ethoxyethylidene)-rhodanine, m.p. 168°-171°C.
