Procedure

In a 1 dram vial were combined 3-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)benzoic acid (30 mg, 0.077 mmol), biphenyl-2-amine (17 mg, 0.10 mmol), and HATU (40 mg, 0.105 mmol). DMF (0.4 mL) and DIPEA (50 μL, 0.29 mmol) were added, and the vial was capped and stirred at r.t. for overnight, then diluted with MeOH, filtered, and purified directly by prep HPLC. Concentration afforded the title compound (17 mg, 41% yield) as a fluffy white solid. 1H NMR (500 MHz, DMSO-d6) δ ppm 9.96 (s, 1H) 8.53 (q, J=4.58 Hz, 1H) 7.96-8.06 (m, 3H) 7.85-7.91 (m, 2H) 7.80 (d, J=8.55 Hz, 1 h) 7.77 (d, J=7.32 Hz, 1H) 7.70 (dd, J=8.55, 1.83 Hz, 1H) 7.57-7.61 (m, 1H) 7.56 (d, J=6.10 Hz, 1H) 7.48 (d, J=7.32 Hz, 2H) 7.36-7.46 (m, 7H) 7.31 (t, J=7.48 Hz, 1H) 2.87 (d, J=4.88 Hz, 3H). LC/MS was performed by using 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=2 min, stop time=3 min, flow rate=4 ml/min, column: Sunfire C18 5 μm 4.6×50 mm; HPLC Rt=2.02 min, (ES+) m/z (MH+)=541. Analytical HPLC method: solvent A=5% CH3CN/95% H2O/0.1% TFA, solvent B=95% CH3CN/5% H2O/0.1% TFA, start % B=10, final % B=100, gradient time=15 min, stop time=18 min, flow rate=1 ml/min. Column: Waters Sunfire C-18, 3.5 μm 4.6×150 mm, Rt=15.37 min, purity=100%; column: Waters Xbridge Phenyl 3.5 μm 4.6×150 mm, Rt=13.75 min, purity=100%.
