実験手順
Following a procedure similar to that for the preparation of 2-trimethylsilanyl-ethyl 4-[3-(8,8-dimethyl-5-p-tolyl-7,8-dihydro-naphthalen-2-yl)-3-oxo-propenyl]-3-fluoro-benzoate (Compound 8) while using 1-(3,3-dimethyl-1-p-tolyl-3H-inden-5-yl)-ethanone (Compound 14, 200 mg, 0.72 mmol) as the starting material yielded the title compound (145 mg, 38% yield) as a yellow solid:
