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 {2-[(3-amino-phenyl)-methyl-amino]-ethyl}-methyl-carbamic acid tert-butyl ester (prepared in three steps from 3-fluoro-1-nitrobenzene and N,N′-dimethylethylenediamine) 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)-methyl-carbamic acid tert-butyl ester (Example 3, step d), according to the method of Example 3, step e. 1H NMR (CDCl3) 8.09 (1H, s), 7.50-7.45 (2H, m), 7.29-7.24 (1H, m), 7.12-7.01 (3H, m), 6.53-6.46 (2H, m), 4.69-4.67 (2H, m), 4.38 (1H, d, 13.8), 4.17 (1H, d, 13.8), 3.50-3.44 (2H, m), 2.93 (3H, s), 2.86-2.74 (3H, m), 2.49 (3H, s), 2.04-1.58 (7H, m), 1.31-1.19 (13H, m). Found: C, 65.52; H, 7.53; N, 14.12%; C32H44N6O5.0.4CH2Cl2 requires: C, 65.58; H, 7.61; N, 14.17%.
