Reaction Steps

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 methanol. 50 μL of sulfuric acid 99% were added. The reaction mixture was stirred at room temperature for 48 hours. A mixture of dichloromethane (10 mL) and water (5 mL) was added. After separation, the aqueous phase was extracted twice with dichloromethane. The combined organic phases were washed with 5 mL of water, dried over magnesium sulfate, filtered, concentrated to yield to 0.150 g of crude material, which was purified by chromatography on silica gel to yield 0.107 g (63%) of desired product N-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1-methoxyethyl}-2-(trifluoromethyl)benzamide (Ia-111), [M+1]=427.
