Treatment of 2‐benzothiazolinethione with excess ethylene oxide in acetic acid resulted in N ‐hydroxyethylation and thiono‐oxo replacement to give 3‐(2‐hydroxyethyl)‐2‐benzothiazolinone. This product was also obtained when S‐alkylthiobenzothiazoles were treated in this way. Similar treatment of the N ‐substituted compounds 3‐methyl‐2‐benzothiazolinethione and 3‐(2‐hydroxyethyl)‐2‐benzothiazolinethione gave simple thiono‐oxo replacement.
