Procedure
To {(S)-1-[3-Hydroxy-6,6-dimethyl-1-(pyridine-2-sulfonyl)-azepan-4-ylcarbamoyl]-3-methyl-butyl}-carbamic acid tert-butyl ester of Example 92h (0.22 g, 0.43 mmol) was added HCl/dioxane (4M, 20 ml, 80 mmol). The mixture was stirred at r.t. for 2 h before solvents and excess amount of HCl was removed on rotavapor. The resulting white solid was dissolved in 5 ml DMF. To the solution was added 2-benzofurancarboxylic acid (84 mg, 0.52 mmol), HBTU (0.2 g, 0.52 mmol) and NMM (0.2 g, 2 mmol). The mixture was stirred at r.t. overnight. DMF was then removed and the residue was redissolved in EtOAc (50 ml), washed with 10% NaHCO3 (50 ml×2) and brine (50 ml). Evaporation of the solvent gave crude product 0.26 g. Purification by column chromatograghy gave the title compound 0.15 g in 63% total yield; MS (M+H+): 556.8; 1H-NMR (400 MHz, CDCl3): •8.66-8.63(m, 1H), 7.94-7.11(m, 10H), 4.72(m, 1H), 4.01-2.98(m, 7H), 1.78-1.39(m, 5H), 1.02-0.85(m, 12H).
