反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 6.32 millimol of 1,4-naphthoquinone and 3.16 millimol of 2,4-dimethyl-3-ethylpyrrole were stirred in 20 ml of glacial acetic acid in a round-bottomed flask for 10 minutes at room temperature. The reaction mixture was diluted with 300 ml of dichloromethane and the resulting mixture was then poured into a large volume of water (300 ml). The organic phase was then separated out and washed four times with 100 ml of water and finally with saturated aqueous NaCl solution. The resulting organic phase was dried over Na2SO4 and then concentrated under vacuum. The product 2-(4-ethyl-3,5-dimethyl-1H-pyrrol-2-yl)-[1,4]-naphthoquinone was thus isolated in a yield of 80% after purification by chromatography on a column of silica. The organic phase was then separated out and washed four times with 100 ml of water The resulting organic phase was dried over Na2SO4 concentrated under vacuum
