实验步骤: The 4-{4,4-Dimethyl-1-[6-(4-trifluoromethyl-phenyl)-pyridin-3-yl]-pentyloxy}-benzoic acid (95 mg, 0.21 mmol), chloro-dimethoxy-triazine (CDMT) (37 mg, 0.21 mmol), and 4-methylmorpholine (25 uL, 0.23 mmol) are combined in anhydrous DCM under nitrogen. The reaction is allowed to stir under nitrogen at room temperature overnight. 3-Amino-butyric acid methyl ester (26 mg, 0.23 mmol) and 4-methylmorpholine (50 uL, 0.47 mmol) is then added to the reaction mixture, and allowed to stir at room temperature. Some water (<10% volume) is added to help solubility. The reaction is monitored by HPLC, and upon complete consumption of the acid, the reaction is diluted with DCM and water and rinsed with 1N HCl. The organic layer is washed with water and brine, dried over anhydrous sodium sulfate, then filtered and concentrated. The 3-(4-{4,4-dimethyl-1-[6-(4-trifluoromethyl-phenyl)-pyridin-3-yl]-pentyloxy}-benzoylamino)-butyric acid methyl ester is isolated after column chromatography. to stir at room temperature upon complete consumption of the acid the reaction is diluted with DCM and water rinsed with 1N HCl The organic layer is washed with water and brine dried over anhydrous sodium sulfate filtered concentrated
