1,2,3,3a,5,9b-Hexahydrocyclopenta[c]quinolin-4-one (153 mg, 0.82 mmol) and Lawesson's reagent (363 mg, 0.9 mmol) are stirred in dimethoxyethane (20 ml) at room temperature. After 3 hours, another portion of Lawesson's reagent (363 mg, 0.9 mmol) is added to it. After 3 hours, the batch is concentrated by evaporation, and the residue is purified by column chromatography on silica gel (eluant: hexane-ethyl acetate).
