Reaction Steps

Anhydrous toluene (100 ml), 5% platinum on carbon (Pt/C) (1.5 g), and 2,3-dimethyl-5-nitro-6-phenoxy-N-(2-phenoxyethyl)pyridin-4-amine (2.97 g) from Part C were placed in a Parr hydrogenation flask at a hydrogen pressure of 345 kPa for 4 hours with shaking. Additional 5% Pt/C (1.5 g) was added and the reaction was allowed to continue for 3 hours. 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 oil was used in the next step.
