Procedure

To N-(6-chloro-4-methylpyridin-2-yl)-1-(2,3-dihydrobenzofuran-5-yl)cyclopropanecarboxamide (150 mg, 0.46 mmol) in 1,2-dimethoxyethane (4 mL) was added 2-methoxypyridin-4-ylboronic acid (84 mg, 0.55 mmol), tetrakis(triphenylphosphine)palladium (0) (53 mg, 0.046 mmol), and 2 M Na2CO3 (680 μL, 1.4 mmol). The reaction mixture was irradiated in the microwave at 120° C. for 20 minutes. The reaction mixture was evaporated to dryness and the residue was purified by silica gel chromatography eluting with (0-20% ethyl acetate/hexanes) to yield 1-(2,3-dihydrobenzofuran-5-yl)-N-(2′-methoxy-4-methyl-2,4′-bipyridin-6-yl)cyclopropanecarboxamide (76 mg, 42%). ESI-MS m/z calc. 401.2. found 402.3 (M+1)+. Retention time 1.88 minutes.
