Abstract

PURPOSE: To obtain the titled compound useful as an anti-inflammatory and analgesic agent in a very high yield, only by removing the protecting group of a novel 2-benzothiazolinone compound obtained easily from 5-chloro-2-benzothiazolinone and a piperazine compound.
CONSTITUTION: 5-Chloro-2-benzothiazolinone of formulaIis reacted with a piperazine compound of formula II (X is halogen or organic sulfonyl; Y is a protecting group of an alcoholic hydroxyl group), e.g. N-chloroacetyl-N'-benzoyloxyethyl-piperazine, in the presence of an alkaline condensing agent, e.g. anhydrous potassium carbonate, to give a novel 2-benzothiazolinone compound of formula III, which is then subjected to the removal of the protecting group to afford a 2-benzothiazolinone derivative of formula IV or a salt thereof.
