Reaction Steps

A 12.36 g portion of benzindanone (63 mmole) was dissolved in 300 ml of THF and 150 ml of methanol, and 3.6 g (95 mmole) of sodium borohydride was added at room temperature. After stirring the mixture for 6 hours, the reaction was terminated with dilute hydrochloric acid, and extracted with hexane (100 ml X 2) and ether (100 ml×2). Two stereoisomers of benzindanol were obtained. The crude product was used for the next reaction without purification.
