Abstract:Fluorobenzyl bromide was used as the starting material to generate 3 via Grignard reaction and bromination reaction. Compound 3 was treated with 2-oxo-2,4,5,6,7,7a-hexahydrothieno[3,2-c]pyridine hydrochloride through condensation, acetylation reaction to give the target compound 1. The target compund 1 was obtained with an overall yield of 30.9%. Reaction conditions including the ratio of the raw materials, the amount of catalyst, reaction time were evaluated to make the reaction conditions mild and easy to control with less side effects. The structure of compound 1 was confirmed by IR, 1H NMR and MS.
Key words:prasugrel; antiplatelet agents; fluorobenzyi bromide
