Procedimiento

A mixture of 22 g. of 3-phenyl-3-(4-nitrophenyl)propenoic acid, 11.7 g. of thionyl chloride and 150 ml. of benzene was heated under reflux for 1 hour. The solvent was removed by evaporation in vacuo, and the residual solid was recrystallized from carbon tetrachloride. This afforded 20 g. of the title compound, m.p. 117°-120° C.
