Versuchsvorschrift

Sulfonamide 44 (20 mg, 40 μmol), 10% aqueous NaOH solution (0.36 mL, 0.9 mmol) in EtOH (1.0 mL) was refluxed for 30 min. The mixture was cooled, concentrated, treated with glacial acetic acid (0.72 mL, 12 mmol), and concentrated again. The residue was separated by LCMS (column LUNA 10 μ C18(2) 00G-4253-V0 250×50 mm) using water—MeCN (0.11% AcOH) as eluent (in gradient; flow 80 mL/min) to afford 45 (3.88 mg, 27%). 1H NMR (400 MHz; CDCl3+3 drops of CD3OD) δ 7.36 (dd, J=7.5, 2.5 Hz, 1H), 7.57 (s, 2H), 7.78 (s, 1H), 8.02 (d, J=2.0 Hz, 1H), 8.15 (d, J=1.8 Hz, 1H), 8.20 (d, J=1.9 Hz, 1H), 8.39 (d, J=2.1 Hz, 1H), 8.50 (s, 1H); MS (ES) m/z 406.3 (MH++MeCN).
