Reaction of 2,3,4,5,6,7-hexahydrothieno[3,2-c]pyridin-2-one p-toluenesulfonate (VII) with TBDMS-Cl and TEA in dichloromethane gives the silylated enol ether (VIII), which is condensed with 1-cyclopropyl-2-chloro-2-(2-fluorophenyl)ethanone (IX) by means of TEA in the same solvent to provide the adduct (X). Finally, this compound is treated with TEA and DMAP and acetylated with Ac2O.
