Participants

Reaction Steps

30 g cis-1,2,3,6-tetrahydrophtalic acid anhydride in 150 ml abs. THF are added through a separating funnel to a solution of 45 g lithium aluminum hydride in 900 ml abs. THF and heated for 48 hours under reflux. Then the mixture is first cooled to room temperature and then in an ice-brine bath to about 15° C. and the unused portion of the hydride is carefully broken down with water. Through the addition of diluted sulphuric acid the salts are dissolved and through the addition of diethylether the organic phase is separated from the aqueous phase.
