Versuchsvorschrift
The product from Example 129 (3 g) was treated with a solution of trimethylsilyl polyphosphate (PPSE) (50 ml in o-dichlorobenzene) at 100° C. for 10 minutes. The reaction was cooled to 0° C., quenched with 2NHCl and extracted with methylene chloride. The organic layer was separated, dried and evaporated to one-half the volume and purified on a small bed of silica gel. The desired tetralone was obtained in 40% yield. m.p.
