Reaction Steps
5.0 g of 6-chloro-2,4-diisopropyl-3-nitropyridine are dissolved in 100 ml of tetrahydrofuran and, after the addition of 2.75 g of triethylamine and 7.5 g of 5% palladium/carbon catalyst, hydrogenated under normal pressure at from +20° C. to +25° C. The reaction mixture is filtered over diatomaceous earth and the filtrate is concentrated. The residue is purified by column chromatography on silica gel (eluant: ethyl acetate/hexane 1:3). 2,4-Diisopropyl-3-aminopyridine is obtained in the form of a waxlike solid, m.p. 35°-39° C.
