Procedure

The rhodanine is reacted as described in Examples 1 and 3 with triethylorthophenylacetate in acetic anhydride to yield 3-(3',4'-dichlorophenyl)-5-(1'-ethoxy-2'-phenylethylidene)-rhodanine which is similarly hydrolyzed to 3-(3',4'-dichlorophenyl)-5-(1'-hydroxy-2'-phenylethylidene)-rhodanine.
