Reaction Steps

The title compound was obtained as the hydrochloride salt 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 2-[(3-amino-phenyl)-tert-butoxycarbonyl-amino]-propionic acid methyl ester (prepared in two steps from 3-nitro-N-tert-butoxycarbonylaniline) was used instead of 3-amino-benzoic acid methyl ester in step e, followed by reaction of the product obtained, in place 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}-phenyl)-propyl-carbamic acid tert-butyl ester (Example 41, step a) according to the method of Example 41, step b. 1NMR (DMSO-d6) 9.53 (1H, s), 7.50 (2H, m), 7.25 (2H, m), 6.98 (2H, m), 6.73 (1H, d), 6.30 (1H, d), 5.00 (3H, br s), 4.79 (2H, s), 4.25 (1H, m), 3.91 (2H, m), 2.86 (1H, m), 2.00-1.00 (10H, m), 1.33 (3H, d), 1.13 (9H, s). Found: C, 60.48; H, 6.77; N, 11.18%; C31H39N5O5.HCl.H2O requires: C, 60.43; H, 6.87; N, 11.37%.
