Abstract

PURPOSE: In the presence of a condensing agent, the reaction between 4-substituted- 2-halogenobenzothiazole and a lower alkyl alcohol is conducted to give readily title compound used for an intermediate of bactericidal agent for agriculture in high yield.
CONSTITUTION: The condensation reaction between a 4-substituted-2-halogenobenzothiazole of formula I (R is halogen, alkyl; X is halogen) and an alcohol of formula II (R' is lower alkyl) is effected in the presence of a basic condensing agent as alkali metal hydroxide or cyclic tertiary amine under a mild condition to form 4-substituted-2-alkoxybenzothiazole of formula III. Even when water coexists, the 2-hydroxy derivative, the hydrolyzate, hardly produces and the objective product can be obtained almost quantitatively. Anhydrous alcohol, the complicated preparation of alkali metal alkoxide, the use of expensive alkali metal, which are required for conventional processes, are unnecessary.
