Abstract

N, N-Dimethyl-2-(alkylthio) ethylamines and 3-methylthiazolidines underwent N-methylation both with trimethyloxonium tetrafluoroborate (3a) and with methyl iodide. In the methylation of N, N-dimethyl-o-(methylthio) aniline, the main reaction was S-methylation. On the other hand, in the o-ethylthio derivative, S-methylated product was major with methyl iodide, while N-methylated product was major with 3a. In the N-ethyl or N-benzyl derivative, only S- ...
