Procedure

In a 1 dram vial with stir bar were combined 3-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)benzoic acid (35 mg, 0.090 mmol), DMAP (33 mg, 0.27 mmol), EDC hydrochloride (26 mg, 0.14 mmol), and benzenesulfonamide (43 mg, 0.27 mmol). 1,2-Dichloroethane (1 mL) and DMF (0.3 mL) were added, the vial was capped, and the suspension was stirred at r.t. overnight, over which time the solids dissolved. The reaction was concentrated, filtered, purified by prep HPLC, and concentrated to give 32 mg (67% yield) of the title compound as a white powder. 1H NMR (500 MHz, DMSO-d6) δ ppm 12.78 (br. s., 1H) 8.52 (q, J=4.48 Hz, 1H) 8.24 (s, 1H) 7.97-8.06 (m, 4H) 7.90-7.97 (m, 2H) 7.85 (d, J=7.94 Hz, 1H) 7.74-7.81 (m, 2H) 7.66-7.73 (m, 1H) 7.63 (t, J=7.63 Hz, 2H) 7.58 (t, J=7.63 Hz, 1H) 7.40 (t, J=8.85 Hz, 2H) 2.87 (d, J=4.58 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=1.77 min, (ES+) m/z (MH+)=529. Analytical HPLC were performed using a Shimadzu-VP instrument with UV detection at 220 nm and 254 nm. Analytical HPLC method: solvent A=5% CH3OH/95% H2O/10 mM NH4HCO3, solvent B=95% CH3OH/5% H2O/10 mM NH4HCO3, start % B=10, final % B=100, gradient time=15 min, stop time=18 min, flow rate=1 ml/min. Column: Phenomenex Gemini C18, 4.6 mm, 3 μm, Rt=15.70 min, purity=100%; column: Waters Xbridge Phenyl 4.6×150 mm, 3.5 μm, Rt=14.90 min, purity=99%.
