Reaction Steps
A mixture of methyl 4-[3-(3-phenoxyphenyl)-1,2,4-oxadiazol-5-yl]benzoate (1.69 g), 1 M aqueous sodium hydroxide solution (10 ml), methanol (15 ml) and tetrahydrofuran (15 ml) was stirred at 60° C. for 1 hr. After cooling, 1 M hydrochloric acid was added to acidify the reaction mixture. The crystals were collected by filtration and recrystallized from hexane-tetrahydrofuran to give 4-[3-(3-phenoxyphenyl)-1,2,4-oxadiazol-5-yl]benzoic acid (1.35 g, yield 83%) as colorless crystals. melting point: 292–293° C.
