Potassium sodium tartarate → 2-(2-Hydroxyethyl)-2,3-dihydro-1H-inden-1-ol

Participants

Reaction Steps

A solution of 1-oxoindane-2-acetic acid ethyl ester acid (5 g), described in Example 475, in dry THF (20 ml) is added to a stirred slurry of lithium aluminum hydride (3.6 g) in 120 ml of the same solvent. The reaction mixture is heated at reflux for 36 hr., allowed to cool, and decomposed with 30% aqueous solution of sodium potassium tartrate (14.4 ml). After filtration, the precipitate is washed with THF. The filtrate and washing are dried. Removal of solvent gives an oil which crystallizes from benzene to give the title compound m.p. 80°-82° C.
