実験手順

A solution of 2-chloro-N-(2-methylpropyl)-3-nitro-4-quinolinamine (120 g), acetic acid (300 mL), isopropyl alcohol (300 mL), and 5% platinum on carbon (7.2 g) was allowed to stand at room temperature for 30 h under 2 bars of hydrogen pressure. The resulting solution was filtered, and the solvent was removed from the filtrate at reduced pressure. The residue was dissolved in aqueous hydrochloric acid (1 L, 4N). The product was precipitated by adding this solution to a solution of sodium hydroxide. The precipitate was filtered and washed with water to afford the product 2-chloro-N4 -(2-methylpropyl)-3,4-quinolinediamine in 73% yield.
