A mixture of 3-(4-bromo-3-chloro-phenyl)-5-(3,5-dichloro-phenyl)-5-trifluoromethyl-4,5-dihydro-isoxazole (4.00 g), palladium bis(diphenylphosphine) dichloride CH2Cl2-complex (0.69 g), palladium acetate (0.14 g), sodium acetate (1.03 g), and methanol (50 mL) was placed in an autoclave, charged with 5 bar of carbon monoxide and stirred at 100° C. for 16 h. After cooling, the autoclave was opened and the reaction mixture was filtered. The filtrate was concentrated in vacuum and the residue was purified by flash chromatography on silica gel to obtain the title compound (2.2 g, 58%).
