1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → 4-((1-benzhydrylpiperidin-4-yl)methoxy)-5-cyclopropyl-2-fluoro-N-(methylsulfonyl)benzamide

Participants

Reaction Steps

A solution of 4-((1-benzhydrylpiperidin-4-yl)methoxy)-5-cyclopropyl-2-fluorobenzoic acid (270 mg, 0.59 mmol), methanesulfonamide (84 mg, 0.88 mmol), EDCI (169 mg, 0.88 mmol) and DMAP (107 mg, 0.88 mmol) in DCM (5 mL) was stirred at room temperature for 16 h. The reaction was quenched with water (5 mL) then adjusted pH to 1 with HCl (1 M). The resulting mixture was extracted with DCM (5 mL×3), dried over anhydrous sodium sulfate, filtered and concentrated. The resulting residue was purified by reverse phase Combiflash (20%-50% CH3CN/H2O in 0.1% NH4HCO3) to afford the target compound (15 mg, 5%) as a white solid. LCMS (ESI) Method A: RT=6.10 min, m/z: 537.2 [M+H]+. 1H-NMR (500 MHz, MeOD-d4,): δ 7.40-7.42 (m, 4H), 7.15-7.30 (m, 7H), 6.67 (d, J=13 Hz, 1H), 4.30 (s, 1H), 3.87 (d, J=6 Hz, 2H), 2.82 (s, 3H), 1.73-1.98 (m, 7H), 1.37-1.40 (m, 3H), 0.83-0.86 (m, 2H), 0.50-0.53 (m, 2H).
