Abstract

Hydroxyethylation of 2-aminobenzothiazoles by ethylene chlorohydrin unexpectedly led to preferential formation of 3-β-chloroethylbenzothiazolin-2-one. In the case of unsubstituted 2-aminobenzothiazole, we also isolated the target 2-indeno-3-β-hydroxyethylbenzothiazoline and bis[(3-β-hydroxyethyl)benzothiazolyl-2-indenelamnionium chloride. As a result of reaction of 2-aminobenzothiazole with 3-β-chloroethylbenzothiazolin-2-one, we obtained 2-(benzothiazolyl-2-imino)-3-(β-(2-oxobenzothiazolin-3-yl)ethyllbenzothiazoline. The structure of the synthesized compounds was established based on X-ray diffraction, PMR, IR, UV, and mass spectra.
