실험 절차

Concentrated sulfuric acid (11.5 μL) was added to a solution of (8S)-2-{(E)-2-[6-methoxy-5-(4-methyl-1H-imidazol-1-yl)pyridin-2-yl]vinyl}-8-(2-trifluoromethylphenyl)-5,6,7,8-tetrahydro-[1,2,4]triazolo[1,5-a]pyridine (98.09 mg) in ethanol (1 mL), and 1 mL of ethyl acetate was added with stirring at room temperature. Since the oily portion was confirmed on the bottom of the recovery flask, the oily substance was dissolved by ultrasonic treatment. Stirring at room temperature under shading for about 30 minutes resulted in precipitation of a solid. The solid was collected by filtration through a glass filter and dried under reduced pressure at room temperature to obtain 127.94 mg of the title compound as white solid crystals.
