-
Paragraph 0036; 0037, (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.
