  • Publication number: 20130030183
    Abstract: The object of the present invention is a one-pot process for preparing the 2-acetoxy-5-(2-fluoro-?-cyclopropyl-carbonyl-benzyl)-4,5,6,7-tetrahydro-4H-tieno[3,2-c]-pyridine (prasugrel) of the formula (I) by reacting the 5,6,7,7a-tetrahydro-4H-tieno[3,2-c]-pyridine-2-on of the formula (II) with 2-bromo-1-cyclopropyl-2-(2-fluorophenyl)-etanone of the formula (III) or with 2-chloro-1-cyclopropyl-2-(2-fluorphenyl)-etanone of the formula (IIIa) and acetylating of the formed compound of the formula (IV), wherein the reaction is carried out in the presence of an organic base with an acetylation agent without isolating the compound of the formula (IV). The coupling and acetylation are carried out in the presence of the same organic base such as triethylamine, N,N-diisopropyl-ethylamine or pyridine. At the end of the process the prasugrel of the formula (I) is purified by recrystallization from an organic solvent or a mixture of solvents.
