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 tert-butylsulfonamide (37 mg, 0.27 mmol). 1,2-Dichloroethane (1 mL) and DMF (0.3 mL) were added, the vial was capped, and the reaction was stirred at r.t. overnight. The reaction was concentrated, filtered, purified by prep HPLC, and concentrated on a speedvac to give 14 mg (31% yield) of the title compound as a white powder. 1H NMR (500 MHz, CDCl3) δ ppm 8.12 (s, 1 H) 7.97 (s, 1 H) 7.91 (dd, J=8.55, 5.19 Hz, 2 H) 7.84 (d, J=7.63 Hz, 1 H) 7.79 (d, J=7.32 Hz, 1 H) 7.46-7.59 (m, 3 H) 7.19 (t, J=8.55 Hz, 2 H) 6.04 (br. s., 1 H) 2.99 (d, J=4.58 Hz, 3 H) 1.54 (s, 9 H). 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=1.71 min, (ES+) m/z (MH+)=509. 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=16.49 min, purity=100%; column: Waters Xbridge Phenyl 4.6×150 mm, 3.5 μm, Rt=15.35 min, purity=100%.
