Reaction Steps

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 [5-cyclohexyl-1-(2-cyclopentyl-2-oxo-ethyl)-2-oxo-1,2-dihydro-3H-1,3,4-benzotriazepin-3-yl]-acetic acid (Example 22, step a) and (6-amino-indol-1-yl)-acetic acid ethyl ester were used 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 (Example 1, step d) and 3-amino-benzoic acid methyl ester respectively 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) 9.65 (1H, s), 7.67 (1H, s), 7.58-7.47 (2H, m), 7.39 (1H, d), 7.28-7.15 (3H, m), 6.97 (1H, d), 6.31 (1H, d), 4.75-4.55 (4H, m), 4.30 (1H, br d), 3.95 (1H, br d), 3.00-2.88 (2H, m), 1.98-1.40 (14H, m), 1.35-1.10 (4H, m). The compound was further characterised as the N-methyl-D-glucamine salt. Found: C, 58.53; H, 6.80; N, 10.01%; C33H37N5O5.C7H17NO5.2.0H2O requires C, 58.95; H, 7.17; N, 10.31%.
