Procedure

To a suspension of 1-(2,3-dihydrobenzofuran-5-yl)-N-(2′-methoxy-3,4-dimethyl-2,3′-bipyridin-6-yl)cyclopropanecarboxamide (105 mg, 0.25 mmol) in CH3CN (5.0 mL) was added TMSI (71.7 μL, 0.50 mmol) drop wise. The reaction was stirred at 55° C. for 1 hour. Methanol (1.0 mL) was added followed by ethyl acetate (6 mL). The organic layer was washed with NaHSO3 (2×), and brine (1×). The organic layer was dried over Na2SO4, filtered and evaporated under reduced pressure. The crude product was purified by column chromatography on silica gel (0-10% methanol in dichloromethane) to yield 1-(2,3-dihydrobenzofuran-5-yl)-N-(4,5-dimethyl-6-(2-oxo-1,2-dihydropyridin-3-yl)pyridin-2-yl)cyclopropanecarboxamide as a white solid (82 mg, 81%). ESI-MS m/z calc. 401.5. found 402.5 (M+1)+. Retention time 1.18 minutes.
