Reaction Steps

A solution of 2-[1-(4-pyridyl)piperidin-4-ylmethylaminocarbonyl]amino-nitrobenzene (1.02 g, 2.87 mmol) in ethanol was hydrogenated at atmospheric pressure over 5% palladium-on-carbon. After completion (16-20 h), the mixture was filtered through diatomaceous earth, using hot ethyl acetate to wash the filter cake. Concentration of the filtrate in vacuo yielded 930 mg (99%) of the title compound.
