Method for preparing 4-substituted-N-methylbenzothiazolone derivatives

A process for producing N-alkylbenzothiazolone derivatives of the formula (I), STR1 wherein R1 is a hydrogen, chlorine, bromine, fluorine atom or a methyl group, and R2 is an alkyl group having 1 to 5 carbon atoms, from 2-halogenobenzothiazole derivatives of the formula (II), STR2 wherein R1 is as defined above and X is a chlorine, bromine or fluorine atom, which is a starting material, through the intermediate of 2-alkoxybenzothiazole derivatives of the formula (III), STR3 wherein R1 and R2 are as defined above, or benzothiazolone derivatives of the formula (IV), STR4 wherein R1 is as defined above.
