Empagliflozin intermediate preparation method

The invention discloses an empagliflozin intermediate preparation method, which comprises: carrying out substitution by using p-methoxybenzyl chloride and p-iodoaniline as starting raw materials to obtain a compound IV, performing diazotization and a Sandmeyer reaction to obtain a compound III, further performing demethylation under the action of boron tribromide to obtain a compound II, and finally performing condensation with (S)-3-p-toluenesulfonyloxy tetrahydrofuran to obtain the target compound I, wherein the product purity is greater than or equal to 99.0%. According to the invention, the preparation method has advantages of simple and easily available raw materials, low cost, simple operation steps, simple post-treatment and high product yield, and is suitable for industrial production.
