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-biphenyl-3-carboxylic acid ethyl ester (prepared in two steps from 3-nitrophenylboronic acid) 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 (CDCl3) 8.40 (1H, s), 8.29 (1H, t), 8.12-8.08 (1H, m), 7.85-7.81 (1H, m), 7.64-7.61 (1H, m), 7.57-7.47 (4H, m), 7.41-7.27 (3H, m), 7.06 (1H, d), 4.80 (1H, d), 4.65 (1H, d), 4.39 (1H, d), 4.25 (1H, d), 2.84-2.77 (1H, m), 2.02-1.70 (6H, m), 1.44-1.16 (13H, m). The compound was further characterised as the N-methyl-D-glucamine salt. Found: C, 61.19; H, 7.07; N, 8.48%; C35H38N4O5.C7H17NO5.1.9H2O requires: C, 61.21; H, 7.19; N, 8.50%.
