Versuchsvorschrift
The compound was prepared according to GP-2 using 2-sulfamoylbenzoic acid ethyl ester 4 and compound 3a. The crude product was purified by flash column chromatography using MeOH—CHCl3 to obtain 5a. 1H NMR (500 MHz, DMSO-d6) δ 9.43 (bs, 2H), 8.49-8.46 (m, 4H), 7.87 (t, J=8.0 Hz, 2H), 7.68 (d, J=7.5 Hz 1H), 7.64 (d, J=8.0 Hz 1H), 7.49 (t, J=7.5 Hz, 1H), 7.33 (t, J=7.5 Hz, 1H), 4.02 (t, J=7.5, 2H), 2.76 (q, J=7.0 Hz, 2H), 1.90-1.60 (m, 2H). MS (ES−) m/z 437 (M−H)−.
