Participants

Reaction Steps

A solution of methyl 4-[3-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydro-isoxazol-5-yl]-2-nitrobenzoate (1 g, 0.43 mmol) and lithium hydroxide (73 mg) in tetrahydrofuran (20 ml) and water (10 ml) was stirred for 1 hour at room temperature. Tetrahydrofuran was then removed and the residue was extracted with ethyl acetate (2×25 ml). The combined organic layers were dried over sodium sulfate and concentrated to give 4-[3-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydro-isoxazol-5-yl]-2-nitrobenzoic acid (0.75 g), 1H-NMR (400 MHz, DMSO): 7.85-7.87 (2H, m), 7.82 (1H, m), 7.66-7.69 (1H, m), 7.61-7.62 (2H, m), 4.22-4.46 (2H, m) ppm.
