실험 절차

Employing the same general procedure as for the preparation of 6-ethynyl-3,4-dihydro-4,4-dimethylnaphthalen-1(2H)-one (Compound K), 2.1 g (8.8 mmol) of 7-bromo-1,1-dimethyl-1,2,3,4-tetrahydronaphthalene was converted into the title compound using 10 ml (93.9 mmol) of trimethylsilyl acetylene, 1.25 g (1.8 mmol) of bis(triphenylphosphine)palladium(II) chloride, 0.53 g (2.8 mmol) of cuprous iodide and 10 ml (20.0 mmol) of K2CO3 (2M solution in methanol).
