To N-(6-chloro-4-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (59 mg, 0.16 mmol), 6-methoxy-4-methylpyridin-3-ylboronic acid (40 mg, 0.24 mmol) and tetrakis(triphenylphosphine)palladium (0) (9 mg, 0.008 mmol) in 1,2-dimethoxyethane (1.63 mL), aqueous saturated Na2CO3 (163 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-4,4′-dimethyl-2,3′-bipyridin-6-yl)cyclopropanecarboxamide (38 mg, 52%). ESI-MS m/z calc. 453.44. found 454.5 (M+1)+. Retention time 2.01 minutes.
