実験手順
To a solution of ethyl (3S)-3-[4-[[2-(2,6-dimethylphenyl)-[1,2,4]triazolo[1,5-a]pyridin-6-yl]methoxy]phenyl]hex-4-ynoate (0.22 g, 0.47 mmol) in EtOH (20 mL) is added 5 N NaOH (0.3 mL) and the reaction mixture is stirred at 80° C. in a microwave instrument for 30 minutes. The reaction mixture is evaporated to dryness, diluted with water, and acidified with 6 N HCl solution to pH ˜3. The precipitated solid is filtered, washed with n-pentane, and dried to give the title compound as a white solid (0.155 g, 75%). LCMS m/z 440 (M+H)+.
