実験手順
4-Fluoro-2-methyl-1-nitrobenzene (2.3 mL, 19 mmol) was added to a suspension of furo[3,2-c]pyridin-4(5H)-one (2.115 g, 15.67 mmol) and Cs2CO3 (5.097 g, 15.67 mmol) in anhydrous DMF (100 mL) and the resulting suspension was heated to 125° C. and stirred for 15 h. H2O was added and the aqueous suspension was filtered. The solid was dried under reduced pressure to afford 4.6 g of crude 5-(3-methyl-4-nitrophenyl)furo[3,2-c]pyridin-4(5H)-one, which was used without further purification.
