反応手順

Carbon monoxide was bubbled through a mixture of 4-(3-bromo-5-chloropyridin-4-ylamino)-8-(cyclopentyloxy)-7-methoxy-2H-chromen-2-one (0.240 g, 0.514 mmol, Example 11), Pd(OAc)2 (11 mg, 0.051 mmol), DPPP (21 mg, 0.051 mmol), triethylamine (0.22 mL, 1.5 mmol), methanol (1 mL), and anhydrous DMF (4 mL). The reaction was heated at 80° C. for 2 d under an atmosphere of CO and then allowed to cool to rt. The mixture was filtered though Celite, washed with EtOAc, and concentrated to give methyl 5-chloro-4-(8-(cyclopentyloxy)-7-methoxy-2-oxo-2H-chromen-4-ylamino)nicotinate.
