Procedure

To a suspension of 1.72 g of LiAlH4 (45.03 mmole) in 100 ml of ether was added dropwise a solution of 10.7 g of methyl 6-tert-butyl-1-indanacetate (36.9 mmole) dissolved in 50 ml of ether. After refluxing the suspension during 2 h, 8.6 ml of 1N NaOH were carefully added and, after 1 h, the suspension was filtered and concentrated to give 9.05 g of raw 2-(6-tert-butyl-1-indanyl)-1-ethanol 78.1% pure. Bulb-to-bulb distillation (150°/20 Pa) provided 8.53 g of 2-(6-tert-butyl-1-indanyl)-1-ethanol with a GC purity of 82.3%. Yield of the last three steps: 71.0%.
