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 → HCID 16732441, compound

Participants

Reaction Steps

The title compound was obtained as the trifluoroacetate 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 (4-amino-indazol-2-yl)-acetic acid tert-butyl ester (prepared in two steps from 4-nitro-indazole) was used instead of 3-amino-benzoic acid methyl ester in step e, followed by reaction of the product obtained, in place of (4-{2-[5-cyclohexyl-1-(3,3-dimethyl-2-oxo-butyl)-2-oxo-1,2-dihydro-3H-1,3,4-benzotriazepin-3-yl]-acetylamino}-indazol-1-yl)-acetic acid tert-butyl ester (Example 130, step a), according to the method of Example 130, step b. 1H NMR (CDCl3) 10.04-9.95 (2H, br s), 9.06 (1H, s), 8.13 (1H, s), 7.53-7.20 (6H, m), 7.06 (1H, d, 6), 5.26 (2H, s), 4.80 (1H, d, 18), 4.63 (1H, d, 18), 4.29 (2H, s), 2.81-2.78 (1H, m), 2.07-1.67 (6H, m), 1.37-1.19 (13H, m). Found: C, 56.82; H, 5.42; N, 11.88%; C31H36N6O5.CF3CO2H.0.7H2O requires: C, 56.72; H, 5.53; N, 12.03%.
