1-Benzyl-4-[N-ethyl-N-(3-nitro-2-pyridinyl)amino]piperidine (EXAMPLE 204, Part A, 1.0 g, 3.05 mmol) is dissolved in ethanol (170 ml) and 0.25 g of platinum oxide is added. The reaction is placed on a Parr hydrogenator at 10 psi for 1 hr and then it is filtered through diatomaceous earth and concentrated under reduced pressure to give the title compound, NMR (300 MHz, CD3OD) 7.52, 7.17, 6.97, 6.79, 3.37, 3.02, 2.94, 2.75, 1.90, 1.60, 1.52 and 0.74δ.
