실험 절차

To a solution of 4-[5-(3,5-Dichloro-phenyl)-5-trifluoromethyl-4,5-dihydro-isoxazol-3-yl]-2-methyl-benzaldehyde-oxime ((i.e. the product of Example 1 Step 2, 177 mg, 0.42 mmol) in DMF (4 mL) was added N-chlorosuccinimide (67 mg, 0.50 mmol) and the mixture was stirred at 70° C. bath temperature for 30 min. After cooling to 0° C., picolylamine (85 mg, 0.79 mmol) and triethylamine (145 mg, 1.44 mmol) was added. The mixture was allowed to war to room temperature over night and was then poured on ice water. The pH was adjusted to 7 by addition of NH4Cl and the resulting precipitate was filtered off. The crude product was then purified by column chromatography on SiO2 (CH2Cl2: MeOH=96:4) to give the title compound (75 mg, 42%).
