実験手順

2-Butyl-3-oxo-2,3,5,6,7,8-hexahydroisoquinoline-4-carbonitrile (7-013) (80 mg, 0.35 mmol) was dissolved in toluene (8 mL), and to the reaction mixture was added Lawesson's reagent (169 mg, 0.42 mmol), the reaction mixture was heated under reflux for 12 h. The reaction mixture was cooled to room temperature, and methanol was added to the reaction mixture, and the reaction mixture was stirred at room temperature for 1 h, and evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give 2-butyl-3-thioxo-2,3,5,6,7,8-hexahydroisoquinoline-4-carbonitrile (7-014) (63 mg, 73%) as a pale brown powder.
