Versuchsvorschrift

In a 7 mL scintillation vial were combined 3-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)benzoic acid (30 mg, 0.077 mmol), 1-amino-N-(cyclopropylsulfonyl)cyclopropanecarboxamide hydrochloride (20 mg, 0.083 mmol), and HATU (40 mg, 0.10 mmol). DMF (0.4 mL) and DIPEA (0.1 mL, 0.57 mmol) were added, the vial was capped, and the solution was stirred at r.t. for 45 min. The reaction was diluted with MeOH, filtered, purified by prep HPLC, and the collected fractions were concentrated on a speedvac to afford the title compound (23 mg, 52% yield) as a white powder. 1H NMR (500 MHz, DMSO-d6) δ ppm 8.99 (br. s., 1H) 8.53 (q, J=4.78 Hz, 1H) 8.25 (br. s., 1H) 8.00 (dd, J=8.85, 5.49 Hz, 2H) 7.93 (s, 1H) 7.89 (t, J=7.78 Hz, 2H) 7.72-7.83 (m, 2H) 7.58 (t, J=7.48 Hz, 1H) 7.40 (t, J=8.85 Hz, 2H) 7.07 (br. s., 1H) 2.89-2.98 (m, 1H) 2.87 (d, J=4.58 Hz, 3H) 1.35-1.56 (m, 2H) 0.77-1.28 (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=1.59 min, (ES+) m/z (MH+)=576. 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=15.39 min, purity=100%; column: Waters Xbridge Phenyl 4.6×150 mm, 3.5 μm, Rt=14.50 min, purity=100%.
