Procedure

To N-(6-chloro-4,5-dimethylpyridin-2-yl)-1-(2,3-dihydrobenzofuran-5-yl)cyclopropanecarboxamide (100 mg, 0.29 mmol), 6-methoxypyridin-3-ylboronic acid (67 mg, 0.44 mmol) and tetrakis(triphenylphosphine)palladium (0) (34 mg, 0.029 mmol) in 1,2-dimethoxyethane (3.0 mL), 2 M Na2CO3 (438 μL, 0.87 mmol) was added. The reaction mixture was stirred and heated at 80° C. for 15 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 (0-30% ethyl acetate in hexane) to yield 1-(2,3-dihydrobenzofuran-5-yl)-N-(6′-methoxy-3,4-dimethyl-2,3′-bipyridin-6-yl)cyclopropanecarboxamide as a white solid (105 mg, 86.6%). ESI-MS m/z calc. 415.5. found 416.5 (M+1)+. Retention time 1.66 minutes.
