Versuchsvorschrift

1-Benzyl-4-[N-ethyl-N-(6-chloro-5-nitro-4-pyrimidinyl)amino]piperidine (EXAMPLE 252, 3.00 g) is dissolved in 150 ml of ethanol and 0.75 g of palladium hydroxide is added. The reaction is placed on a Parr hydrogenator at 10 psi for 1 h, then filtered through diatemous earth and concentrated under reduced pressure. Purification by flash column chromatography (5% methanol/chloroform) gives the title compound.
