실험 절차

To a solution of 2-Methyl-4-[5-trifluoromethyl-5-(3-trifluoromethyl-phenyl)-4,5-dihydro-isoxazol-3-yl]-benzaldehyde oxime (250 mg) in DMF (8 mL) was added N-chloro succinimide (84 mg) and heated to 75° C. for 1 h. After cooling, the reaction mixture was poured onto water and extracted with EtOAc. The combined organic layers were dried (Na2SO4) and concentrated in vacuo to ¼ of the original volume to obtain the crude hydroxamic acid chloride. This mixture was added to a solution of 2-amino-N-(2,2,2-trifluoro-ethyl)-acetamide (116 mg) and triethylamine (0.30 mL, 0.21 g) in THF (8 mL) and stirred at room temperature over night. After concentration in vacuo, the mixture was purified by chromatography on silica gel to obtain the title compound (146 mg, 43%).
