Versuchsvorschrift

Accordingly, 1,2,3,9-tetrahydro-9-methyl-3-methylene-4H-carbazol-4-one was synthesized from 1,2,3,9-tetrahydro-9-methyl-4H-carbazol-4-one using a formaldehyde reagent (paraformaldehyde) and a mineral acid (HCl) in an aprotic solvent (DMF). Note that this reaction was rapid and high yielding, even though it was performed without using glacial acetic acid as a solvent, and without using a secondary amine as a catalyst.
