Abstract
PURPOSE: To obtain the titled compound which is an analgesic and an anit-inflammatory agents, etc. in high purity and high yield, by reacting a novel 5-chloro- 2-trialkylstannyloxybenzothiazole with an N-hydroxyethyl-N'-substituted acetylpiperazine.
CONSTITUTION: 5-Chloro-2-benzothiazolinone is reacted with an N-hydroxyethyl- N'-substituted acetylpiperazine to give a 5-chloro-2-benzothiazolinone derivative. In the process, a novel 5-chloro-2-trialkylstannyloxybenzothiazole obtained by reacting 5-chloro-2-benzothiazolinone with a trialkyltin compound, e.g. bis(tri-ethyltin) oxide or bis(tri-propyltin)oxide, is reacted with an N-hydroxyethyl-N'-substituted acetylpiperazine.
