Procedure

144 mg (3.8 mmol) of lithium aluminum hydride and 50 ml of THF were introduced into a three-necked flask and under a nitrogen stream. Next, a solution of 1.4 g (3.8 mmol) of ethyl 4-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydro-2-naphthylthio)benzoate in 25 ml of THF was introduced dropwise and the mixture was heated at reflux for 8 hours. The excess hydride was destroyed with a potassium sodium tartrate solution and the reaction medium was extracted with ethyl acetate. The organic phase was decanted off, dried over magnesium sulfate and evaporated.
