Ozagrel (INN) is an antiplatelet agent working as a thromboxane A2 synthesis inhibitor.^[1]

Synthesis

The free-radical halogenation of ethyl 4-methylcinnamate (1) with N-bromosuccinimide in the presence of benzoyl peroxide gives ethyl 4-bromomethylcinnamate (2).^[2] Alkylation of imidazole (3) with this material gives the ethyl ester (4) of the drug, which is saponified to give ozagrel.^[3]^[4]
