A solution of N-(6-chloro-4,5-dimethylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (38 mg, 0.1 mmol) in DME (1 mL) was added to a reaction tube containing 2-methoxypyridin-4-ylboronic acid (46 mg, 0.15 mmol) and Pd(PPh3)4 (6 mg, 0.005 mmol). Saturated Na2CO3 solution was added (100 μL) and the reaction was stirred at 80° C. overnight. The reaction was filtered, concentrated and purified by column chromatography (0-50% ethyl acetate in hexanes) to obtain 40 mg (44%) of a clear oil. ESI-MS m/z calc. 453.4. found 454.3 (M+1)+.
