Vorschrift

A solution of 2-chloro-4-(4-(3-(4-fluoro-3-methoxyphenyl)thioureido)-2-methyl-3-oxobutan-2-yl)benzenesulfonamide (8.6 g, 18.1 mmol) in AcOH (100 mL) was refluxed 3 h. After the reaction was complete, the solution was cooled to room temperature and azeotroped with toluene. The residue was triturated with Et2O, filtered and dried to provide the title compound (6.8 g, 82% yield) as a light yellow solid. 1H NMR (400 MHz, CDCl3+MeOD) δ 7.92 (d, J=8.4 Hz, 1H), 7.09 (s, 1H), 7.06 (d, J=8.4 Hz, 1H), 6.97 (t, J=8.4 Hz, 1H), 6.89 (s, 1H), 6.38 (m, 1H), 6.13 (d, J=7.2 Hz, 1H), 3.58 (s, 3H), 1.54 (s, 6H); MS (EI) m/z 456 (MH+).
