Procedure:
1-phenylcyclopropanamine hydrochloride (16 mg, 0.091 mmol) was added to a stirring solution of HATU (43 mg, 0.114 mmol), DIEA (40 μL, 0.228 mmol), and 3-(2-(4-fluorophenyl)-6-(N-(2-hydroxyethyl)methylsulfonamido)-3-(methylcarbamoyl)benzofuran-5-yl)benzoic acid (40 mg, 0.076 mmol) in DMF (760 μL) at rt. It was allowed to stir for 1 hour. The mixture was diluted with EtOAc and washed with sat NaHCO3, and sat NaCl. The organic phase was dried over Na2SO4, filtered and concentrated and was purified by preparative reverse phase HPLC on a C18 column using a suitably buffered H2O/CH3CN gradient, and concentrated to give the titled compound (22 mg, 44%). 1H NMR (500 MHz, DMSO-d6) d ppm 9.12 (1H, s), 8.49-8.56 (1H, m), 7.97-8.05 (3H, m), 7.95 (1H, s), 7.90 (1H, d, J=7.93 Hz), 7.78 (1H, d, J=7.93 Hz), 7.62 (1H, s), 7.54 (1H, t, J=7.78 Hz), 7.37-7.46 (2H, m), 7.28 (2H, t, J=7.63 Hz), 7.19-7.24 (2H, m), 7.15 (1H, t, J=7.32 Hz), 4.90 (1H, t, J=5.19 Hz), 3.50-3.58 (1H, m), 3.25-3.28 (1H, m), 3.21 (3H, s), 2.88-2.96 (2H, m), 2.82 (3H, d, J=4.58 Hz), 1.22-1.32 (4H, m). LC-MS retention time: 1.57 min; m/z (MH+): 642. LC data was recorded on a Shimadzu LC-10AS liquid chromatograph equipped with a Waters XBridge 5 u C18 4.6×50 mm column using a SPD-10AV UV-Vis detector at a detector wave length of 220 nM. The elution conditions employed a flow rate of 5 ml/min, a gradient of 100% solvent A/0% solvent B to 0% solvent A/100% solvent B, a gradient time of 2 min, a hold time of 1 min, and an analysis time of 3 min where solvent A was 5% acetonitrile/95% H2O/10 mM ammonium acetate and solvent B was 5% H2O/95% acetonitrile/10 mM ammonium acetate. MS data was determined using a Micromass Platform for LC in electrospray mode. Additional 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, 4.6×150 mm, 3.5 mm, Rt=11.28 min, purity=99%; Column: Waters Xbridge Phenyl column 4.6×150 mm, 3.5 mm, Rt=10.86 min, purity=98%.
