실험 절차

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 N-methylbenzenesulfonamide (50 μL, 0.26 mmol). 1,2-Dichloroethane (0.5 mL) and DMF (0.5 mL) were added, the vial was capped, and the reaction was stirred at r.t. overnight. The reaction was filtered, purified by prep HPLC, and concentrated on a SPEEDVAC® to give 27 mg (55% yield) of the title compound as a white powder. 1H NMR (500 MHz, CDCl3) δ ppm 7.91-8.02 (m, 5H) 7.75-7.82 (m, 2H) 7.65 (t, J=7.48 Hz, 1H) 7.47-7.60 (m, 6H) 7.15-7.24 (m, 2H) 5.91 (d, J=4.27 Hz, 1H) 3.36 (s, 3H) 3.04 (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=1.89 min, (ES+) m/z (MH+)=543. 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=17.42 min, purity=92%; column: Waters XBridge phenyl 4.6×150 mm, 3.5 μm, Rt=17.86 min, purity>90%.
