실험 절차

To a solution of (5Z)-5-(piperidin-4-ylmethylidene)-4-(prop-2-yn-1-ylamino)-1,3-thiazol-2(5H)-one dihydrochloride (200 mg) in DMF (3 mL) were added triethylamine (0.35 mL) and 2-(trifluoromethoxy)benzaldehyde (0.09 mL). The reaction mixture was stirred at room temperature for 1 hr, and sodium triacetoxyborohydride (554 mg) was added. The reaction mixture was stirred at room temperature for 3 hr, saturated aqueous sodium hydrogen carbonate solution was added, and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) and recrystallized from ethyl acetate/heptane to give the title compound (69 mg).
