Procedure

N-(6-Chloro-5-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (110 mg, 0.300 mmol) was dissolved in 3 mL of 1,2-dimethoxyethane (DME) in a microwave reactor tube. 2-Methoxypyridin-3-ylboronic acid (59.6 mg, 0.390 mmol), 0.4 mL of an aqueous 2 M potassium carbonate solution, and tetrakis(triphenylphospine)palladium(0) (Pd(PPh3)4, 34.7 mg, 0.0300 mmol) were added and the reaction mixture was heated at 120° C. in a microwave reactor for 20 minutes. The resulting material was cooled to room temperature, filtered, and the layers were separated. The crude product was evaporated to dryness, dissolved in 1 mL of N,N-dimethylformamide, and purified by reverse-phase preparative liquid chromatography utilizing a gradient of 0-99% acetonitrile in water containing 0.05% trifluoracetic acid to yield 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(2′-methoxy-3-methyl-2,3′-bipyridin-6-yl)cyclopropanecarboxamide. ESI-MS m/z calc. 439.1. found 440.1 (M+1)+. Retention time 1.94 minutes.
