Sodium Hydroxide → HCID 21461393, compound

Participants

Reaction Steps

A solution of 30.9 g (~0.14 mol) of crude (1RS,2SR,4RS)-1,7,7-trimethyl-2-(2-methyl-oxiranylmethyl)bicyclo[2.2.1]heptan-2-ol in 100 ml of anhydrous diethyl ether was added dropwise to 11.0 g (0.29 mol) of lithium aluminum hydride suspended in 300 ml of the same solvent under reflux, and under nitrogen. The reaction mixture was stirred overnight at room temperature and treated with 60 ml of 2M sodium hydroxide solution. The white precipitate was filtered out, washed with diethyl ether and the combined organic phases were washed with 2×200 ml of water and 200 ml of brine. After drying (MgSO4) and evaporation of solvent the crude (1RS,2SR,4RS)-2-(2-hydroxy-2-methylpropyl)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-ol (29.0 g of white waxy solid; two step yield 92%) was used in the next steps without further purification.
