실험 절차

0.16 g of N-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]ethylidene}-2-(trifluoromethyl)benzamide (Int-6) were diluted in 2 mL of acetic acid. The reaction mixture was stirred for two days at room temperature and then heated to 90° C. for one day and left at room temperature for four days. After concentration in vacuo, the crude product was purified by chromatography on silica gel to yield 0.045 g (24%) of desired product 2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1-{[2-(trifluoromethyl)benzoyl]amino}ethyl acetate (Ia-112), [M+1]=455.
