Reaction Steps

To N-(6-chloro-5-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (200 mg, 0.54 mmol), 2-methoxy-6-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (408 mg, 1.64 mmol) and tetrakis(triphenylphosphine)palladium (0) (64 mg, 0.055 mmol) in 1,2-dimethoxyethane (3.3 mL), 2 M Na2CO3 (818.0 μL, 1.636 mmol) was added. The reaction mixture was stirred and heated at 80° C. for 68 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 (0-15% ethyl acetate in hexane) to yield 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(2′-methoxy-3,6′-dimethyl-2,4′-bipyridin-6-yl)cyclopropanecarboxamide (0.214 g, 86.5%). ESI-MS m/z calc. 453.4. found 454.5 (M+1)+. Retention time 1.81 minutes.
