Reaction Steps

The synthesis process is as set forth in the chemical reaction formula below. To 5,6,7,8-tetrahydro-2-hydroxy-5,5,8,8-tetramethylnaphthalene (204 mg, 1.00 mol) were added anhydrous dichloromethane (1 mL), aluminum chloride (148 mg, 1.12 mmol), and isobutyryl chloride (117 mg, 1.10 mmol) followed by stirring at 60° C. for 2 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 (20/1) as an elution solvent. The yield was 128 mg (47%).
