실험 절차

A solution of 4-[5-(3,5-dichloro-phenyl)-5-trifluoromethyl-4,5-dihydro-isoxazol-3-yl]-2-methyl-benzaldehyde (i.e. the product of Step 1, 500 mg), concentrated hydrochloric acid (5 drops) and 2-picolyl hydrazine (188 mg) in methanol (20 mL) were heated at reflux for 5 h. The mixture was concentrated and the residue was triturated with water. Filtration yielded the title compound (289 mg, 45%).
