To N-(6-chloro-4,5-dimethylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (70 mg, 0.18 mmol), 2-methoxy-3-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (69 mg, 0.27 mmol) and tetrakis(triphenylphosphine)palladium (0) (21 mg, 0.018 mmol) in 1,2-dimethoxyethane (2.0 mL), 2 M Na2CO3 (276 μL, 0.55 mmol) was added. The reaction mixture was stirred and heated at 80° C. for 20 hours under N2 atmosphere. The reaction mixture was diluted with ethyl acetate (5 mL), 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-3,4,5′-trimethyl-2,3′-bipyridin-6-yl)cyclopropanecarboxamide (50 mg, 58%). ESI-MS m/z calc. 467.4. found 468.7 (M+1)+. Retention time 1.96 minutes.
