To N-(6-chloro-4-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (88 mg, 0.24 mmol) in 1,2-dimethoxyethane (2.5 mL) was added 6-methoxy-2-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (144 mg, 0.29 mmol), tetrakis(triphenylphosphine)palladium (0) (28 mg, 0.024 mmol), and 2 M Na2CO3 (361.2 μL, 0.72 mmol). The reaction mixture was irradiated in the microwave at 120° C. for 20 minutes. The reaction mixture was evaporated to dryness and purified by silica gel chromatography eluting with (0-20% ethyl acetate in hexane) to yield 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(6′-methoxy-2′,4-dimethyl-2,3′-bipyridin-6-yl)cyclopropanecarboxamide (70 mg, 61%). ESI-MS m/z calc. 453.44. found 454.3 (M+1)+. Retention time 1.89 minutes.
