Procedure

The title compound was prepared from t-butyldimethyl-silyloxy-2,6-dipropyl-4-vinylbenzene (Step B, Example 14) by treatment with tetrabutylammonium fluoride in THF for a few hours. It was poured into ether/ethyl acetate mixture and washed with brine. After removal of the solvent the crude product was purified by flash column chromatography using ethyl acetate/hexane as eluent.
