Procedure
N-(4-(N-(5-Sulfamoyl-1,3,4-thiadiazol-2-yl)sulfamoyl)phenyl)decanamide 139). 5-(4-Aminophenylsulfonamido)-1,3,4-thiadiazole-2-sulfonamide (7, 50 mg, 0.15 mmol) was suspended in anhydrous acetonitrile (5 mL). Triethylamine (17.1 mg, 0.17 mmol) was added with stirring at 0° C. A solution of decanoyl chloride (32.4 mg, 0.17 mmol) dissolved in anhydrous acetonitrile (1 mL) was added dropwise, and the reaction mixture was stirred at 0° C. for 2 h and overnight at room temperature. Volatiles were removed in vacuo and the residue was washed with water (5 mL). The residue was subjected to chromatography on silica gel (70-230 mesh) eluted with CH2Cl2:methanol 9:1, giving the pure product as a solid (42 mg, 0.09 mmol, 60% yield), mp 242-243° C.; 1H NMR (300 MHz, DMSO-d6) δ 0.84 (t, 3H, J=6.9 Hz), 1.24 (m, 12H), 1.56 (m, 2H), 2.32 (t, 2H, J=7.5 Hz), 7.66 (s, 4H), 7.91 (s, 2H), 10.13 (s, 1H); 13C NMR (75 MHz, DMSO-d6) δ 14.1, 22.3, 25.2, 28.8, 29.0, 31.5, 36.6, 118.6, 127.0, 137.4, 142.2, 157.8, 170.8, 172.1; LRMS (LCQ, ESI−) calcd for C18H26N5O5S3 488.1, found 488.1 (M−H)−; HRMS (ESI−, m/z) calcd for C18H26N5O5S3 488.1102, found 487.1101 (M−H)−.
