20.00 g (56.59 mmol, 1.0 eq) 2-nitro-N-[1-(phenylmethyl)-4-piperidinyl]-phenylacetamide from Example 1 are placed in 280 mL 2-methyltetrahydrofuran. The solution is hydrogenated in the presence of 2.00 g platinum dioxide at 20° C. The catalyst is filtered off and washed with 20 ml of 2-methyltetrahydrofuran. The product is not isolated, but used as a solution in the next step.
