実験手順

A mixture of 4-(chloromethyl)-3-(2,6-dichlorophenyl)-5-(1-methylethyl)isoxazole (152 mg, 0.5 mmol), cesium carbonate (489 mg, 1.5 mmol) and 4-mercaptophenyl boronic acid (75 mg, 0.5 mmol) in dimethylformamide (5 mL) was allowed to stir for 24 hours in a 60° C. oil bath. The mixture was diluted with ethyl acetate and washed with water. The organic layer was washed with brine, dried with magnesium sulfate, filtered and concentrated to yield 277 mg of crude [4-({[3-(2,6-dichlorophenyl)-5-(1-methylethyl)-4-isoxazolyl]methyl}thio)phenyl]boronic acid and dimethylformamide. 1H NMR (400 MHz, d6-DMSO): δ 7.63-7.59 (m, 4H), 7.55-7.51 (m, 1H), 7.17 (d, J=8 Hz, 2H), 3.86 (s, 2H), 3.12 (septet, J=7 Hz, 1H), 1.13 (d, J=7 Hz, 6H).
