Procedure:
To a 25 mL flask was added 2′-chloro-4-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)-5-methylbiphenyl-2-carboxylic acid (47.2 mg, 0.087 mmol), DMF (2 mL), N-ethyl-N,N-diisopropyl propan-2-amine (0.061 mL, 0.349 mmol), 1-(pyridin-2-yl)cyclopropanamine (17.56 mg, 0.131 mmol) and finally HATU (2-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V), 133 mg, 0.349 mmol). The flask was sealed with a septa, placed under N2 and stirred at room temperature for 5 hours. The crude product was purified using a Shimadzu preparative HPLC employing acetonitrile/water/trifluoroacetic acid where solvent A was 10% acetonitrile/90% water/0.1% trifluoroacetic acid and solvent B was 10% water/90% acetonitrile/0.1% trifluoroacetic acid with a Waters Sunfire 5 μm C18 19×150 mm column at a gradient of 30-100% B and a flow rate of 25 mL/min. over 20 minutes with a 10 minute hold. The solvent was evaporated to give 66.1 mgs (92% yield) of 5-(2′-chloro-5-methyl-2-(1-(pyridin-2-yl)cyclopropyl carbamoyl)biphenyl-4-yl)-2-(4-fluorophenyl)-N-methylbenzofuran-3-carboxamide as a white solid. The LC/MS data was obtained on a Shimadzu analytical LC/MICROMASS® Platform LC (ESI+) at 220 nm using the following set of conditions: PHENOMENEX® Luna 3 μm C18, 2×50 mm column, with a gradient of 0-100% B (B=90% HPLC grade acetonitrile/0.1% trifluoroacetic acid/10% HPLC grade water), (A=90% HPLC grade water/0.1% trifluoroacetic acid/10% HPLC grade acetonitrile), in 4 minutes with a 1 minute hold at a rate of 0.8 mL/minute. HPLC purity was determined using a Shimadzu analytical LC at 254 nm and 256 nm with a Waters Sunfire C18 3.5 μm 4.6×150 mm column employing water/acetonitrile/trifluoroacetic acid with a gradient of 10-100% B (B=95% HPLC grade acetonitrile/0.1% trifluoroacetic acid/5% HPLC grade water), (A=95% HPLC grade water/0.1% trifluoroacetic acid/5% HPLC grade acetonitrile), in 10 minutes with a 10 minute hold at a rate of 1 mL/minute. The HPLC purity was then confirmed with an orthogonal solvent system and column using a Shimadzu analytical LC with a Waters XBridge phenyl C18 3.5 μm 4.6×150 mm column employing water/methanol/10 mM ammonium bicarbonate with a gradient of 10-100% B (B=95% HPLC grade methanol/10 mM ammonium bicarbonate/5% HPLC grade water), (A=95% HPLC grade water/10 mM ammonium bicarbonate/5% HPLC grade methanol), in 10 minutes with a 10 minute hold at a rate of 1 mL/minute. 1H NMR (400 MHz, THF-d8) δ ppm 0.85-0.96 (m, 1H), 0.99-1.09 (m, 1H), 1.38-1.53 (m, 2H), 2.33 (s, 3H), 2.90 (d, J=4.52 Hz, 3H), 7.07-7.14 (m, 1H), 7.20-7.28 (m, 3H), 7.30-7.36 (m, 3H), 7.37-7.42 (m, 2H), 7.44-7.49 (m, 1H), 7.56 (d, J=4.52 Hz, 1H), 7.58-7.65 (m, 3H), 7.77 (d, J=1.51 Hz, 1H), 7.89 (s, 1H), 8.10-8.18 (m, 2H), 8.37-8.42 (m, 1H). LCMS m/z 631.39 (M+H), Rt=2.925 min. HPLC (Sunfire C18) Rt=8.118 min, 99.9% purity and (XBridge phenyl C18) Rt=11.519 min., 100% purity.
