Π-Excessive heterocyles react rapidly with bis(dialkylamino)methanes (aminals) and alkoxydialkylaminomethanes (aminol ethers) in acetonitrile to afford Mannnich bases in good yields when ativated by means of an acidi reagent suh as acetyl chloride or sulphur dioxide: the principal ompound studied was N-methylpyrrole.
