Procedure

To N-(6-chloro-5-methylpyridin-2-yl)-1-(2,3-dihydrobenzofuran-5-yl)cyclopropanecarboxamide (95 mg, 0.3 mmol) in 1,2-dimethoxyethane (3 mL) was added 2-methoxypyridin-4-ylboronic acid (66 mg, 0.4 mmol), tetrakis(triphenylphosphine)palladium (0) (33 mg, 0.03 mmol), and 2 M sodium carbonate (0.45 mL, 0.9 mmol). The reaction mixture was irradiated in the microwave at 120° C. for twenty minutes. The reaction mixture 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 crude reaction mixture was purified by silica gel chromatography eluting with (0-50% ethyl acetate/hexanes) to yield the product (42 mg, 34%). ESI-MS m/z calc. 401.17. found 402.5 (M+1)+. Retention time 1.88 minutes.
