The title compound was obtained by the method used in the preparation 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 methyl ester (Example 1) except that (3-amino-benzenesulfonyl)-acetic acid ethyl ester (prepared in one step from (3-amino-phenylsulfanyl)-acetic acid ethyl ester) was used instead of 3-amino-benzoic acid methyl ester in step e, followed by reaction of the product obtained, in place of [5-cyclohexyl-1-(3,3-dimethyl-2-oxo-butyl)-2-oxo-1,2-dihydro-3H-1,3,4-benzotriazepin-3-yl]-acetic acid ethyl ester (Example 1, step c), according to the method of Example 1, step d. 1H NMR (DMSO-d6) 13.08 (1H, br s), 10.26 (1H, s), 8.16 (1H, s), 7.77-7.45 (5H, m), 7.26-7.15 (2H, m), 4.80 (2H, m), 4.39 (2H, s), 4.38 (1H, d), 3.98 (1H, d), 2.86 (1H, m), 1.65-1.34 (6H, m), 1.25-1.13 (13H, m). The compound was further characterised as the N-methyl-D-glucamine salt. Found: C, 53.55; H, 6.90; N, 8.48%; C30H36N4O7S.C7H17NO592.0H2O requires: C, 53.67; H, 6.94; N, 8.46%.
