<P>PROBLEM TO BE SOLVED: To provide a method for producing 3-chloro-4-fluorobenzotrifluoride useful as an intermediate of a medicine and an agricultural chemical and as an intermediate of a functional material. Ž<P>SOLUTION: A starting material i.e. 4-fluorotoluene is converted into the intended compound i.e. 3-chloro-4-fluorobenzotrifluoride according to the following processes namely, a first process: a process of causing 4-fluorobenzotrichloride and hydrogen fluoride (HF) to react with each other to obtain 4-fluorobenzotrifluoride, and a second process: a process of causing 4-fluorobenzotrifluoride and chlorine (Cl<SB>2</SB>) to react with each other to obtain 3-chloro-4-fluorobenzotrifluoride.
