Versuchsvorschrift

Methanesulfonamide (96 mg, 1.00 mmol) was added to a solution of 3-{2-[5-cyclohexyl-1-(3,3-dimethyl-2-oxo-butyl)-2-oxo-1,2-dihydro-3H-1,3,4-benzotriazepin-3-yl]-acetylamino}-benzoic acid (Example 2)(409 mg, 0.80 mmol), EDC (207 mg, 1.08 mmol) and DMAP (122 mg, 1.00 mmol) in DCM (20 ml) at room temperature. After stirring for 17 h, the mixture was washed with 5% KHSO4 (50 ml), brine (50 ml) and dried (MgSO4). Filtration and evaporation of the solvent gave the crude product which was purified by flash column chromatography (MeOH-DCM (1:10) to afford the title compound as a white crystalline solid (392 mg, 83%). 1H NMR (DMSO-d6) 9.99 (1H, s), 8.02 (1H, s), 7.63-7.36 (5H, m), 7.23 (1H, t), 7.13 (1H, d), 4.73 (2H, dd), 4.29 and 4.25 (2H, d×2), 3.24 (3H, s), 2.87 (1H, m), 1.80-1.48 (6H, m), 1.30-1.09 (13H, m). The compound was further characterised as the N-methyl-D-glucamine salt. Found: C, 53.93; H, 7.07; N, 10.17%; C30H37N5O6S.C7H17NO5.2.0H2O requires: C, 53.74; H, 7.07; N, 10.16%.
