Procedure

A mixture of methyl 3-[5-(4-chlorophenyl)-3-isoxazolyl]benzoate (1.10 g), 1 M aqueous sodium hydroxide solution (5 ml), tetrahydrofuran (15 ml) and methanol (15 ml) was stirred at 60° C. for 1 hr. After cooling, the reaction mixture was poured into water, and 1 M hydrochloric acid (5 ml) was added. The crystals were collected by filtration and recrystallized from tetrahydrofuran-hexane to give 3-[5-(4-chlorophenyl)-3-isoxazolyl]benzoic acid (0.91 g, yield 87%) as colorless crystals. melting point: 298–299° C.
