실험 절차

To a solution of 3-{2-ethyl-3-[(E)-2-(methyloxy)ethenyl]phenyl}-5-[4-[(1-methylethyl)oxy]-3-(trifluoromethyl)phenyl]-1,2,4-thiadiazole (D49) (140 mg) in tetrahydrofuran (THF) (10 mL) stirred under nitrogen at room temperature was added hydrochloric acid (0.2 mL). The reaction mixture was stirred at 70° C. for 5 h. After cooling the reaction, the solution was condensed under reduced pressure to give (2-ethyl-3-{5-[4-[(1-methylethyl)oxy]-3-(trifluoromethyl)phenyl]-1,2,4-thiadiazol-3-yl}phenyl)acetaldehyde (D50) (108 mg) as a colorless oil, which was used directly in the next step without further purification. MS (ES): C22H21F3N2O2S requires 434. found 435.2 (M+H+).
