Procedure
30.00 kg (90.01 mol) 4-[1-(phenylmethyl)-4-piperidinyl]-morpholine-dihydrochloride (M) were dissolved in 67.5 L methanol and 20.0 L water. Then the mixture was hydrogenated at a pressure of 4 bar and an internal temperature of 50° C. in the presence of 1.80 kg palladium on charcoal until no further uptake of hydrogen could be detected. After the reaction had ended the catalyst was filtered off and washed with a mixture of 18.0 L methanol and 2.0 L water. The hydrogenation solution obtained was then transferred into a reactor and heated to 60° C. At 60° C. 540.0 L ethanol were metered in. The resulting suspension was cooled to 5° C. The product was centrifuged off and dried.
