1H-Indene-3-acetic acid → 1H-Indene-3-ethanol

Participants

Reaction Steps

A suspension is prepared from 3.4 g (0.09 mol) of lithium aluminium hydride in 200 ml of dry diethyl ether. A solution of 7.7 g (0.044 mol) of 1H-indene-3-acetic acid in 150 ml of diethyl ether is added dropwise, and the mixture is stirred and heated at reflux for 20 h. The mixture is cooled, hydrolysed with approximately 8 ml of 10% aqueous sodium potassium tartrate solution, heated at boiling for 1 h and filtered. The residue is rinsed with diethyl ether, and the filtrate is evaporated under reduced pressure. The residue is purified by distillation. 5.2 g of a product are obtained which is used as it is in the following step.
