実験手順

N-(6-Chloro-4-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (73 mg, 0.20 mmol) was dissolved in 2 mL of 1,2-dimethoxyethane in a reaction tube. 2-Methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (55 mg, 0.36 mmol), 0.3 mL of an aqueous 2 M sodium carbonate solution, and tetrakis(triphenylphosphine)palladium(0) (18 mg, 0.015 mmol) were added and the reaction mixture was heated at 80° C. 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 resulting residue was purified by silica gel chromatography eluting with a gradient of 0-100% ethyl acetate in hexane to yield 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(2′-methoxy-4-methyl-2,4′-bipyridin-6-yl)cyclopropanecarboxamide (31 mg, 35%). ESI-MS m/z calc. 439.1. found 440.3 (M+1)+. Retention time 2.12 minutes.
