Procedure

To a solution of [(1R,3S,5R)-1-(2-aza-bicyclo[3.1.0]hex-3-yl)methyl]-carbamic acid 3-chloro-2-fluoro-phenyl ester, trifluoroacetate (prepared as described in Example 115) (60.0 mg, 0.211 mmol) in THF (3 mL) was added HBTU (120 mg, 0.316 mmol), DIPEA (0.147 mL, 0.843 mmol) and (3-acetyl-indol-1-yl)-acetic acid (50 mg, 0.232 mmol). The reaction mixture was stirred at RT for 60 h. Volatiles were removed under reduced pressure and the residue was purified by preparative HPLC (Waters Sunfire, C18-ODB, 5 μm, 30×100 mm, eluent: 20-100% CH3CN/H2O/20 min, 100% CH3CN/2 min, CH3CN and H2O containing 0.1% TFA, flow: 40 mL/min) to give after lyophilization of the purified HPLC fractions the title compound. MS (LC/MS): 484.0 [M+H]+; tR (HPLC conditions k): 3.69 min.
