Procedure

Lithium aluminum hydride (3.56 g., 0.094 mole) is added to a stirred solution of 3-(2-methylpropyl)-4-(phenylmethyl)piperazinone (XL, Example 72, 17.43 g., 0.075 mole) in THF (720 ml.). The solution is refluxed for 5 hours and is then cooled. Ethyl acetate is added and the product is partitioned between ether and water. The ether is removed and the product is distilled to give the title compound, a b.p. of 98° at 0.05 mm pressure.
