実験手順
To a stirred solution of tert-butyl 4-(bromomethyl)-5-chloro-2-fluorobenzoate (Preparation 25, 2.50 g, 7.99 mmol) and 5-chloro-6-cyclopropylpyridin-3-ol (Preparation 42 WO2012007869, 1.13 g, 6.66 mmol) in DMSO (25 mL) was added K2CO3 (2.76 g, 19.9 mmol). The resulting mixture was stirred under nitrogen at room temperature for 18 hours. The reaction mixture was then quenched with water (30 mL) and extracted with EtOAc (2×30 mL). The combined organic layers were washed with water (30 mL), dried over MgSO4 and evaporated under reduced pressure to give the crude product (2.69 g). Purification was accomplished by column chromatography on silica (eluting with 1:9 Et2O/cyclohexane) affording the title compound (1.24 g, 46%).
