Reaction Steps

To N-(6-chloro-4,5-dimethylpyridin-2-yl)-1-(2,3-dihydrobenzofuran-5-yl)cyclopropanecarboxamide (100 mg, 0.29 mmol), 2-methoxypyridin-4-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 16 hours under N2 atmosphere. Product and starting material were observed. 0.5 Equivalents of 2-methoxypyridin-4-ylboronic acid and 0.05 equivalents of tetrakis(triphenylphosphine)palladium (0) were added and continued heating for 40 hours. 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-(2′-methoxy-3,4-dimethyl-2,4′-bipyridin-6-yl)cyclopropanecarboxamide as a yellow solid (107 mg, 88%). ESI-MS m/z calc. 415.5. found 416.7 (M+1)+. Retention time 1.74 minutes.
