反应条件: temp:75.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 2-Chloro-4-[5-(3,5-dichloro-phenyl)-5-trifluoromethyl-4,5-dihydro-isoxazol-3-yl]-benzaldehyde Oxime (i.e. the Product of Step 3, 250 mg) in DMF (5 mL) was added N-chloro succinimide (81 mg) and heated to 75° C. for 1 h. After cooling, the reaction mixture was poured onto ice-water and extracted with EtOAc. The combined organic layers were washed with water, 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-ethyl-acetamide (58 mg) and triethylamine (0.15 mL, 0.11 g) in THF (10 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 (164 mg, 53%). After cooling the reaction mixture was poured onto ice-water extracted with EtOAc The combined organic layers were washed with water dried (Na2SO4) concentrated in vacuo to obtain the crude hydroxamic acid chloride After concentration in vacuo the mixture was purified by chromatography on silica gel

实验步骤: 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 ice-water and extracted with EtOAc. The combined organic layers were washed with water, 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-ethyl-acetamide (61 mg) and triethylamine (0.15 mL, 0.11 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 (171 mg, 55%). After cooling the reaction mixture was poured onto ice-water extracted with EtOAc The combined organic layers were washed with water dried (Na2SO4) concentrated in vacuo to obtain the crude hydroxamic acid chloride After concentration in vacuo the mixture was purified by chromatography on silica gel
