Toluene (150 ml), 5% platinum on carbon (5.0 g), and 2-chloro-5,6-dimethyl-3-nitro-N-(2-phenoxyethyl)pyridin-4-amine (3.32 g) from Part B of Example 1 were placed in a Parr hydrogenation flask at a hydrogen pressure of 345 kPa for 4 hours with shaking. HPLC analysis indicated that the reaction was complete. The reaction mixture was filtered through a fluted filter paper and then through a folded No. 2 Whatman filter. The solvent was removed from the filtrate under reduced pressure and the resulting brown oil was used in the next step.
