A [...] preparation method and intermediate

The present invention relates to a preparation method and an intermediate of ticagrelor. The preparation method comprises that a compound represented by a formula VIII and a compound represented by a formula VII or a salt thereof as raw materials to carry out a reaction, and the obtained intermediate is subjected to acetonylidene protection group removing, optionally substituted azobenzene protection group removing, and cyclization, and then reacts with a compound represented by a formula II or a salt thereof to prepare the ticagrelor. The preparation method of the present invention has characteristics of short step, high total yield, mild reaction conditions and simple post-treatment, and is suitable for industrial production.

INTERMEDIATE OF TICAGRELOR AND PREPARATION METHOD THEREFOR, AND PREPARATION METHOD FOR TICAGRELOR

Disclosed are intermediates of Ticagrelor and a preparation method therefor, and a preparation method for Ticagrelor. Specifically, disclosed is an intermediate, namely, a compound of Formula (VI), for preparing Ticagrelor. Further disclosed is a method for preparing the intermediate and a method for preparing Ticagrelor by using the intermediate. Ticagrelor is prepared by using the intermediate, so that the synthesis process is simple, and a defect that long reaction times under high temperature that are required in the existing methods are avoided. The method is suitable for mass production in industry, energy consumption is reduced, pollution of the environment is reduced, and discharge of waste is reduced.

METHOD FOR THE PREPARATION OF TICAGRELOR AND INTERMEDIATES SUITABLE THEREFORE

A method for the preparation of ticagrelor of formula I, wherein the key reaction of the entire synthesis is condensation of an amino cyclopentane diol with pyrimidine, providing the isolated intermediate of formula IV. The amino cyclopentane diol is used for the reaction with pyrimidine without any protecting group on the hydroxyls in positions 1 and 2. Using the compound without a protecting group eliminates the necessity of deprotection in the subsequent synthetic steps.
