実験手順

Following a procedure similar to that for the preparation of 7-bromo-1,1-dimethyl-4-p-tolyl-1,2-dihydro-naphthalene (Compound 4) while using 5-bromo-3,3-dimethyl-indan-1-one (Compound 12, 1.00 g, 4.2 mmol) as the starting material yielded the title compound (981 mg, 75% yield) as a colorless oil:
