Procedure
A mixture of 4-(2-(4-benzhydrylpiperazin-1-yl)-2-oxoethyl)-5-cyclopropyl-2-fluorobenzoic acid (35 mg, 0.074 mmol), methanesulfonamide (11 mg, 0.11 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (28 mg, 0.15 mmol) and 4-dimethylaminopyridine (18 mg, 0.15 mmol) in dichloromethane (2 mL) was stirred at room temperature for 16 h. The mixture was diluted with DCM (10 mL), washed with HCl (2M, 8 mL) and brine (8 mL), dried over anhydrous sodium sulfate, filtered and concentrated. The residue was purified by Combiflash (30%-40% CH3CN in 0.1% NH4HCO3) to afford target compound (5 mg, 12.3%) as a white solid. LCMS (ESI) Method A: RT=5.17 min, m/z: 550.2 [M+H]+. 1H NMR (500 MHz, DMSO-d6): δ 7.44-7.43 (m, 4H), 7.31-7.26 (m, 5H), 7.21-7.18 (m, 2H), 6.82 (d, J=11.0 Hz, 1H), 4.34 (s, 1H), 3.81 (s, 2H), 3.53 (brs, 4H), 2.88 (s, 3H), 2.28 (brs, 4H), 1.76-1.75 (m, 1H), 0.83-0.81 (m, 2H), 0.51-0.49 (m, 2H).
