Participants

Reaction Steps

To a solution of (S)-(3-fluoro-4-(trifluoromethoxy)phenyl)(3-fluoropyridin-2-yl)methanamine hydrochloride (100 mg, 0.294 mmol, Intermediate 6), 4-(methoxycarbonyl)benzoic acid (52.9 mg, 0.294 mmol), and DMF (2 mL) were added TEA (0.123 mL, 0.881 mmol) and 50% propylphosphonic anhydride in EtOAc (0.175 mL, 0.587 mmol). The solution was stirred at room temperature. After 2 h, the reaction was diluted with water (30 mL), stirred for 30 min, and then filtered. The solids were washed with water and dried in the funnel to give the title compound as a white solid. MS (ESI pos. ion) m/z: 467.0 (M+H).
