Abstract
The reaction of N-thiocarbamoylimidates (1) under bar with methyl thioglycolate leads to the formation of 4-arylamino-5-methoxycarbonylthiazoles (2) under bar. The condensation of the same imidates (1) under bar on ethyl bromoacetate, benzyl bromide and chloroacetonitrile provides the corresponding 2-arylaminothiazoles (4) under bar.
