Procedure

Racemic 4-[1-(4-bromo-phenoxy)-5,5,5-trifluoro-pentyl]-benzoic acid (7.46 g, 17.89 mmol), 2-chloro-4,6-dimethoxy-1,3,5-triazine (3.23 g, 18.43 mmol) and 4-methylmorpholine (2.07 mL, 18.78 mmol) are combined in anhydrous dichloromethane (100 mL) under nitrogen. The reaction is allowed to stir under nitrogen at room temperature overnight. Beta alanine methyl ester hydrochloride (2.76 g, 19.68 mmol) and 4-methylmorpholine (4.14 mL, 37.56 mmol) is 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 dichloromethane. The reaction is diluted with water and rinsed with 1N hydrochloric acid. Upon acidification, the two layers are separated. The organic layer is washed with brine, dried over anhydrous sodium sulfate, and concentrated. Flash column chromatography gave the title compound (7.07 g, 14.1 mmol).
