Procedure

DIPEA (50 μL, 0.29 mmol) and N-methylbenzylamine (20 μL, 0.16 mmol) were added to a stirred suspension of 3-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)benzoic acid (20 mg, 0.051 mmol) and HATU (25 mg, 0.066 mmol) in DMF (0.5 mL) and the reaction was stirred at r.t. overnight. The reaction was then diluted with MeOH, filtered, purified by prep HPLC, and concentrated to give the title compound as a tan powder (12 mg, 47% yield). 1H NMR (500 MHz, DMSO-d6) δ ppm 8.50 (br. s., 1H) 8.01 (dd, J=8.39, 5.65 Hz, 2H) 7.66-7.93 (m, 5H) 7.58 (br. s., 1H) 7.42-7.50 (m, 1H) 7.35-7.42 (m, 4H) 7.31 (d, J=5.80 Hz, 1H) 7.23 (d, J=4.58 Hz, 1H) 4.72 (br. s., 1H) 4.54 (br. s., 1H) 2.83-3.00 (m, 6H). 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=1.85 min, (ES+) m/z (MH+)=493. 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=16.26 min, purity=99%; column: Waters Xbridge Phenyl 3.5 μm 4.6×150 mm, Rt=12.81 min, purity=98%.
