实验过程

A mixture of 50 g. of 3-(3-nitrophenyl)propenoic acid, 24.54 ml. of thionyl chloride and 300 ml. of benzene were heated under reflux for 2.5 hours. The cooled solution was filtered and then it was evaporated in vacuo. The residue was recrystallized from carbon tetrachloride, to give 49.9 g. (91% yield) of the title compound, m.p. 81°-83.5° C.
