1-(Benzo[d][1,3]dioxol-5-yl)-N-(6-chloro-5-methylpyridin-2-yl)cyclopropanecarboxamide (66 mg, 0.20 mmol) was dissolved in 2 mL of 1,2-dimethoxyethane in a reaction tube. 6-Methoxypyridin-3-ylboronic acid (37 mg, 0.24 mmol), 0.2 mL of an aqueous 2 M sodium carbonate solution, and tetrakis(triphenylphosphine)palladium(0) (12 mg, 0.010 mmol) were added and the reaction mixture was heated at 80° C. overnight. The reaction was diluted with ethyl acetate (5 mL) and washed with water (5 mL). The organics were dried over sodium sulfate and evaporated to dryness. The resulting residue was purified by silica gel chromatography eluting with a gradient of 0-100% ethyl acetate in hexane to yield 1-(benzo[d][1,3]dioxol-5-yl)-N-(6′-methoxy-3-methyl-2,3′-bipyridin-6-yl)cyclo-propanecarboxamide (34 mg, 51%). ESI-MS m/z calc. 403.2. found 404.7 (M+1)+. Retention time 1.84 minutes.
