摘要：
A method for producing an alkylthiobenzamide by carrying out a reaction of a halobenzamide with an alkanethiol in the presence of a base in a heterogeneous solvent; a method for producing an alkylsulfinylbenzamide by carrying out a reaction of an alkylthiobenzamide with a halogen in a heterogeneous solvent; a method for producing an alkylsulfinylbenzamide by carrying cut a reaction of a halobenzamide with an alkanethiol in the presence of a base in a heterogeneous solvent and a subsequent reaction with a halogen; and a method for producing a 1,2-benzisothiazol-3-one by carrying out a reaction of a 2-(alkylthio)benzamide with a halogenating agent.
