Procedure

A mixture of 4-((1-benzoylazetidin-3-yl)methoxy)-5-cyclopropyl-2-fluorobenzoic acid (20 mg, 0.05 mmol), EDCI (21 mg, 0.10 mmol), DMAP (12 mg, 0.10 mmol) and methanesulfonamide (9 mg, 0.10 mmol) in DCM (5 mL) was stirred at room temperature for 18 h. The mixture was diluted with DCM (10 mL) and washed with HCl (2 N, 15 mL×2). The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated. The residue was purified by HPLC (20%-30% CH3CN in 0.1% NH4HCO3) to give target compound (4 mg, 17%) as a pale yellow solid. LCMS (ESI) Method A: RT=3.86 min, m/z: 446.5 [M+H]+. 1H-NMR (500 MHz, MeOH-d4,): δ 7.67-7.31 (m, 5H), 7.30 (d, J=8.5 Hz, 1H), 6.89 (d, J=13.0 Hz, 1H), 4.65-3.62 (m, 1H), 4.61-4.22 (m, 5H), 3.36 (s, 3H), 3.25-3.23 (m, 1H), 1.99-1.95 (m, 1H), 0.94-0.61 (m, 4H).
