Reaction Steps

The synthesis process is as set forth in the chemical reaction formula below. To 5,6,7,8-tetrahydro-5,5,8,8-tetramethylnaphthalene (188 mg, 1 mmol) were added anhydrous dichloromethane (1 mL), aluminum chloride (148 mg, 1.12 mmol), and propionyl chloride (101 mg, 1.10 mmol) followed by stirring at 60° C. for 3 hours. The reaction solution was poured into cold water and extracted by ethyl acetate. The organic layer was washed by water, a saturated sodium hydrogen carbonate aq. solution, and a saturated saline solution, dried over magnesium sulfate, and concentrated under reduced pressure. The crude product was purified by silica gel chromatography using hexane/ethyl acetate (30/1) as an elution solvent. The yield was 66.4 mg (27%).
