Prasugrel synthetic method

The invention relates to a synthetic method of prasugrel. 2-bromo-1-cyclopropyl-2-(2-fluorophenyl) acetone and 4,5,6,7-tetrahydro thieno [3,2-C] pyridine hydrochloride are condensed under the action of alkali, so that an intermediate, namely 1-cyclopropyl-2-(6,7-dihydro thieno [3,2-C] pyridine-5(4H)-yl)-2-(2-fluorophenyl) acetone, is obtained, and then oxidation and acylation are carried out, so that prasugrel is obtained. The synthetic method of prasugrel has the advantages that a prasugrel intermediate is synthesized, condensation yield is high, operating steps are simple, protection and deprotection steps in the prior art are eliminated, and cost is greatly saved.
