A method for preparing prasugrel intermediate
-
Paragraph 0042; 0043, (2018/04/01)
The invention provides a preparation method of a Prasugrel intermediate. The method comprises the following steps: performing an amino protection reaction by taking 4,5,6,7-tetrahydrothieno[3,2-c]pyridine hydrochloride as a raw material; and performing a halogenating reaction, an alkylation reaction, a sodium alkoxide deprotection reaction and an HCl gas acidifying reaction to obtain a target compound. The method is simple, advanced in process, small in the quantity of three wastes produced in a production process, low in environmental protection stress, high in yield, and suitable for industrial production.

Clopidogrel is a prodrug anticoagulant with active metabolites that irreversibly inhibit the platelet surface GPCR P2Y12 and thus inhibit platelet activation. However, gaining an understanding of patient response has been limited due to imprecise understanding of metabolite activity and stereochemistry, and a lack of acceptable analytes for quantifying in vivo metabolite formation. Methods for the production of all bioactive metabolites of clopidogrel, their stereochemical assignment, and the development of stable analytes via three conceptually orthogonal routes are disclosed. (Chemical Equation Presented).
