Preparation method of benzofuran derivative

The invention discloses a preparation method for synthesizing a benzofuran derivative. The specific implementation method is as shown in the specification. The method has novel synthetic route, simpleand convenient operation, high yield, and good safety, and is suitable for industrial production. A novel synthetic method of an intermediate VI is also designed, a Wittig reaction is carried out, and then ring-closing is carried out to obtain a benzofuran ring.
