The Uses of 5,6,7,7a-Tetrahydrothieno[3,2-c]pyridine-2(4H)-one hydrochloride
5,6,7,7a-tetrahydrothieno[3,2-c]pyridin-2(4H)-one hydrochloride is used as an intermediate in the synthesis of Prasugrel (P701150).
Synthesis
Hydrochloride (0.32 ml) was added in a solution of 5-Triphenyl methyl-tetrahydro-5, 6, 7,7a 4H- theino-[3,2-c]- pyridone-2 (100 g, 0.25 moles) in acetone (500 ml) at 25 °C. Stir the reaction mass for 1 hr at 50 °C, then cool the reaction mass to 25 °C and stir for 8 to 10 hrs at 25 °C. Filter the product and wash it with acetone. Dry the material under vacuum at 60 °C to obtain 5, 6, 7,7a -Tetrahydro-4H- theino-[3,2-c]- pyridone-2 hydrochloride (42 g, 99percent).
