실험 절차

To N-(6-chloro-5-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (73 mg, 0.2 mmol) in 1,2-dimethoxyethane (2 mL) was added 3-chloro-2-methoxy-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (65 mg, 0.24 mmol), tetrakis(triphenylphosphine)palladium (0) (12 mg, 0.01 mmol), and 2 M sodium carbonate (0.20 mL, 0.4 mmol). The reaction mixture was heated to 80° C. in an oil bath overnight. The reaction mixture was diluted with dichloromethane (5 mL) and washed with water (5 mL). The organics were dried over sodium sulfate and evaporated to dryness. The crude reaction mixture was purified by silica gel chromatography (eluting with 0-100% ethyl acetate in hexanes) to yield the product (26 mg, 27%). ESI-MS m/z calc. 473.86. found 474.3 (M+1)+. Retention time 2.27 minutes.
