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-cyclohexyl-2-oxo-ethyl)-2-oxo-1,2-dihydro-3H-1,3,4-benzotriazepin-3-yl]-acetic acid (Example 79, step a) and (3-amino-phenylsulfanyl)-acetic acid ethyl ester were used instead 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 (CDCl3) 8.44 (1H, s), 7.45 (3H, m), 7.38 (1H, d), 7.24 (2H, m), 7.11 (1H, d), 7.05 (1H, d), 6.70 (1H, br s), 4.70 (1H, d), 4.44 (1H, d), 4.21 (2H, m), 3.66 (2H, s), 2.80 (1H, m), 2.47 (1H, m), 2.18-1.66 (11H, m), 1.44-1.22 (9H, m). The compound was further characterised as the N-methyl-D-glucamine salt. Found: C, 56.91; H, 6.96; N, 8.36%; C32H38N4O5S.C7H17NO5.2.0H2O requires: C, 56.99; H, 7.24; N, 8.52%.
