Procedure

To a 100 mL round-bottomed flask containing 2-fluoro-5-(trifluoromethyl)benzoyl chloride (0.44 ml, 2.9 mmol) in CH2Cl2 (30 mL) was added triethylamine (0.48 ml, 3.4 mmol). After 10 min, 5-amino-2-methylbenzoic acid (0.400 g, 2.6 mmol) was added. The solution was stirred at rt overnight. After cooling, the crude reaction mixture was concentrated to remove excess NEt3 then diluted with CH2Cl2 and washed with 1 N HCl once, and brine & salt once then dried over Na2SO4 to afford 5-(2-fluoro-5-(trifluoromethyl)benzamido)-2-methylbenzoic acid 32 as an off-white solid. MS m/z found: 342.1 (ESI, pos. ion).
