실험 절차

To N-(6-chloro-4-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (0.15 g, 0.41 mmol), 2-methoxy-3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (0.15 g, 0.61 mmol) and tetrakis(triphenylphosphine)palladium (0) (0.024 g, 0.02 mmol) in 1,2-dimethoxyethane (2.46 mL), aqueous saturated Na2CO3 (410 uL) was added. The reaction mixture was stirred and heated at 80° C. for 18 hours under N2 atmosphere. The reaction mixture was diluted with 1,2-dimethoxyethane, dried over Na2SO4, filtered and evaporated under reduced pressure. The crude product was purified by column chromatography on silica gel (0-30% ethyl acetate in hexane) to yield 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(6′-methoxy-4,5′-dimethyl-2,3′-bipyridin-6-yl)cyclopropanecarboxamide (0.075 g, 40%). ESI-MS m/z calc. 453.44. found 454.5 (M+1)+. Retention time 2.24 minutes.
