Reaktionsschritte

Analogously to Example D, 5.0 g (34 mmol) of 2-methyl-1-indanone (5) were reduced with 1.94 g (51 mmol) of NaBH4. The alcohol, which was not purified further, was then further reacted in the presence of 0.2 g of p-toluene-sulfonic acid in 100 ml of toluene at 80° C. Chromatography on 100 g of silica gel (hexane/methylene chloride 9:1) gave 3.68 g (82%) of 2-methylindene (6).
