To a stirred solution of 5-chloro-4-(((5-chloro-6-cyclopropylpyridin-3-yl)oxy)methyl)-2-fluorobenzoic acid (Preparation 27, 500 mg, 1.4 mmol) in dichloromethane (40 mL) was added HATU (639 mg, 1.68 mmol) and N,N-diisopropylethylamine (0.78 mL, 4.49 mmol), the mixture was left to stir for 15 minutes. Azetidine-1-sulfonamide (Preparation 19, 573 mg, 4.21 mmol) was added and the reaction mixture was stirred at room temperature for 18 hours. The reaction mixture was then washed with saturated aqueous NH4Cl (30 mL) and brine (30 mL). The organic layer was dried over MgSO4 and evaporated under reduced pressure to give the crude product as an orange oil. This was purified by column chromatography on silica (eluent 1:1 heptane/EtOAc) to give the title compound as an off-white solid (450 mg, 67%).
