Reaction Conditions

Reaction Steps

A mixture of methyl 3-(5-phenyl-3-isoxazolyl)benzoate (1.30 g), 1 M aqueous sodium hydroxide solution (10 ml), tetrahydrofuran (20 ml) and methanol (10 ml) was stirred at 60° C. for 1 hr. After cooling, the reaction mixture was poured into water, and 1 M hydrochloric acid (10 ml) was added. The crystals were collected by filtration and recrystallized from tetrahydrofuran-hexane to give 3-(5-phenyl-3-isoxazolyl)benzoic acid (1.05 g, yield 85%) as colorless crystals. melting point: 250–251° C.
