The reaction of some
representative N,N-dialkylanilines with N- hydroxymethylphthalimide in concentrated
sulphuric acid solution (the Tscherniac-Einhorn
reaction) has been studied and the structures of the resultant phthalimide
derivatives elucidated (principally by means of p.m.r.
spectroscopy). In some instances, when two equivalents of the reagent were
used, the in corporation of two phthalimidomethyl groups into the
N,N-dialkylaniline molecule was achieved. Similar results were obtained when
the less reactive N-hydroxymethylchloroacetamide was
used as the amidomethylating reagent.
