Procedure

To a solution of 3-(2-(4-fluorophenyl)-3-(methylcarbamoyl)-1H-indol-5-yl)benzoic acid (12 mg, 0.031 mmol) and DIPEA (20 μL, 0.115 mmol) in 1,2-dichloroethane (0.5 mL)/DMF (0.1 mL) was added cumylamine (15 μL, 0.10 mmol) and HATU (15 mg, 0.039 mmol). The reaction was stirred at r.t. for 30 min, then the volatiles were evaporated and the residue was purified directly by prep HPLC. Concentration afforded the title compound as a white powder (11 mg, 68% yield). 1H NMR (500 MHz, MeOD) δ ppm 8.52 (s, 1H) 8.09 (d, J=7.93 Hz, 2H) 7.85 (d, J=7.63 Hz, 1H) 7.66-7.77 (m, 3H) 7.49-7.57 (m, 3H) 7.47 (d, J=8.24 Hz, 2H) 7.31 (t, J=7.78 Hz, 2H) 7.23 (t, J=8.85 Hz, 2 H) 7.19 (t, J=7.32 Hz, 1H) 2.89 (s, 3H) 1.78 (s, 6H). LC/MS was performed on a Shimadzu-VP instrument with UV detection at 220 nm and Waters Micromass. LC/MS method: solvent A=10% CH3CN/90% H2O/0.1% TFA, solvent B=90% CH3CN/10% H2O/0.1% TFA, start % B=0, final % B=100, gradient time=3 min, stop time=4 min, flow rate=4 ml/min, column.
