Reaction Steps

2-Chloro-N-isobutyl-5,6-dimethyl-3-nitropyridin-4-amine (25.8 g, 100 mmol) was combined with 5% platinum on carbon (2.58 g) and ethyl acetate (200 mL) in a pressure vessel and hydrogenated at 50 psi (3.4×105 Pa) for 2.5 hours on a Parr apparatus. The reaction mixture was filtered through CELITE filter agent, which was rinsed with ethyl acetate and methanol afterwards. The filtrate was concentrated to give 2-chloro-N4-isobutyl-5,6-dimethylpyridine-3,4-diamine and was used directly in the next step.
