Disclosed is a method of preparing an intermediate useful for synthesis of a diphenylmethane derivative that can be used as an SGLT inhibitor. A method of synthesizing a compound of Formula 7 according to the present invention can address problems of existing synthesis processes of requiring additional processes, due to synthesis of the Grignard reagent, and management of related substances. In addition, the method according to the present invention can minimize the generation of related substances, and thus does not require reprocessing of reaction products, thereby being capable of simplifying a process. Accordingly, the production yield of a diphenylmethane derivative can be maximized.
