Participants

Reaction Steps

To a slurry of lithium aluminium hydride (17.1 g) in dry diethyl ether (375 ml) under a nitrogen atmosphere, cis-hexahydrophthalimide (23.0 g) in dry tetrahydrofuran (300 ml) was added over a two-hour period. The mixture was refluxed for 2.5 hours, cooled and treated very slowly with excess of water. The precipitate was filtered off and the filtrate was evaporated to yield the title compound as a viscous oil, which was used in the next step without purification.
