To a mixture of 3-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)-5,6-dihydrobenzo[d]isoxazol-7(4H)-one (880 mg, 2.72 mmol) in THF (15 ml) at 0° C., was added slowly (3,5-difluorophenyl)magnesium bromide (6.54 mL of 0.5 M solution in THF, 3.27 mmol) and the reaction was stirred for 3 hr. Additional amount of (3,5-difluorophenyl)magnesium bromide (6.0 mL of 0.5 M solution in THF, 3.0 mmol) was added and stirring was continued at 0° C. for 2 hr. The reaction mixture was quenched with water, extracted with ethyl acetate, and the organic phase was washed with water and brine, dried over sodium sulfate and concentrated. The crude product was purified by silica gel chromatography using 0-6% MeOH in DCM as solvent to afford the 828 mg of the title product.
