A solution of 3-sulfinylamino-N-[2-ethyl-6-methyl-4-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-phenyl]-benzamide (0.111 g, 0.237 mmol) (for example, Example 2.1) in dichloromethane (2 ml) and tetrahydrofuran (2 ml) was treated with aqueous hydrochloric acid (2N) (1 ml) and stirred at 25° C. for 30 minutes. The organic solvents were removed from the reaction mixture under reduced pressure. The residue was neutralized with aqueous sodium hydrogen carbonate (saturated) and was extracted with dichloromethane. The organic phase was dried over sodium sulfate and evaporated to yield the desired compound. 1H-NMR (CDCl3, 400 MHz): 7.44 (s, 1H), 7.38 (s, 2H), 7.30-7.20 (m, 3H), 6.89 (d, 1H), 3.85 (bs, 2H), 2.69 (q, 2H), 2.32 (s, 3H), 1.22 (t, 3H) ppm.
