実験手順
O-4-nitrophenylhydroxylamine (100 mg), was suspended in 0.5 ml acetic acid and 1-(4-methoxyphenyl)-heptane-1,3-dione was added. The mixture was stirred at 70° C. for 3 h and then at 100° C. for an additional 14 h. The mixture was cooled to room temperature and the solvent evaporated under vacuum. Yield 70% of 2-butyl-3-(4-methoxybenzoyl)-5-nitrobenzofuran.
