1,4-Naphthoquinone → HCID 10551488, compound

Participants

Reaction Steps

The same procedure as in Example 7 was followed by stirring 10 millimol of 1,4-naphthoquinone with 2.5 millimol of N-pentylpyrrole in 40 ml of acetic acid at 50° C. for 5 hours. The 1-pentyl-2,5-bis(1,4-naphthoquinon-2-yl)pyrrole was thus obtained in a yield of 87% after chromatography on a column of silica.
