Reaction Steps

1-Methyl-3-(2-methylpropyl-4-(phenylmethyl)piperazinone (Example 47, 2.1 g.) is dissolved in methanol (200 ml.), 10% palladium charcoal (1.0 g.) is added and the product is hydrogenated (50 lb. initial hydrogen pressure until the uptake of hydrogen ceased. The solution is filtered and the methanol is removed under reduced pressure to give the title compound as an oil.
