Procedure

1-{4′-[3-Methyl-4-(4-phenyl-but-1-enyl)-isoxazol-5-yl]-biphenyl-4-yl}-cyclopropanecarboxylic acid ethyl ester (0.343 g, 0.718 mmol) and m-chloroperbenzoic acid (0.181 g, 0.79 mmol) were stirred in CH2Cl2 overnight. An additional portion of m-chloroperbenzoic acid was added and the reaction stirred overnight again. Standard aqueous workup and silica gel chromatography (0-100% EtOAc in hexanes) afforded the title compound.
