Procedure

Preparation B6, Step 4: To a solution of methyl 5-(trifluoromethyl)-2-(trifluoromethylsulfonamido)benzoate (2.7 g, 7.7 mmol) in 55 ml of THF was added lithium hydroxide (0.97 g, 23.1 mmol) in 55 ml of water and stirred at RT over night. The reaction mixture was acidified with 1.5N HCl and extracted with ethyl acetate. The organic layer was washed with water, brine and concentrated to give 5-(trifluoromethyl)-2-(trifluoromethylsulfonamido)benzoic acid (2 g) as white solid. 1H NMR (DMSO-d6, 400 MHz) δ 7.77 (m, 2H), 8.18 (s, 1H). MS found: (M−H)−=336.
