Toremifene synthesis method

The invention provides a synthesis method of toremifene. The synthesis method comprises the following steps: S1. performing McMurry reaction to a compound B as shown in a structural formula II and a compound C as shown in a structural formula III, to obtain a compound D as shown in a structural formula IV; S2. performing selective alkylation reaction of phenolic hydroxyl to the compound D and a compound E as shown in a structural formula V or hydrochloride of the compound E, to obtain a compound F as shown in a structural formula VI; and S3. reacting the compound F with thionyl chloride, to obtain the toremifene, wherein the structural formula II, the structural formula III, the structural formula IV, the structural formula V and the structural formula VI are respectively shown in the specification. The obtained compound D has higher stereoselectivity, therefore, the reaction yield of the toremifene with a Z configuration can be increased when the compound D serves as an intermediate to synthesize the toremifene, and the purity of the toremifene with the Z configuration can be improved; and the synthesis method is stable in technology, mild in reaction conditions, the intermediate is easily separated, and the synthesis method can be used for mass production.
