Reaction Steps

A mixture of ethyl 4-[5-(4-chlorophenyl)-2-thienyl]benzoate (1.03 g), 1 M aqueous sodium hydroxide solution (4.5 ml), tetrahydrofuran (30 ml) and ethanol (30 ml) was stirred at 60° C. for 1.5 hrs. After cooling, the reaction mixture was poured into water, and 1 M hydrochloric acid (15 ml) was added. The crystals were collected by filtration and recrystallized from ethanol to give 4-[5-(4-chlorophenyl)-2-thienyl]benzoic acid (0.566 g, yield 60%) as a pale-green crystalline powder. melting point: 285–286° C.
