Nitric Acid → 8-Chloro-2-methyl-5-nitroquinoline

関与物質

反応手順

53.3 g (0.3 mole) of the resulting 8-chloroquinaldine was dissolved in 180.2 g of 98% sulfuric acid, and at 40° C., 40.2 g of nitric acid (specific gravity 1.50) was added dropwise over the course of 1 hour, followed by further reaction for 30 minutes. The reaction mixture was poured into ice water, and neutralized with an aqueous solution of sodium hydroxide. The product precipitated was collected by filtration, washed with water, and dried to afford 64.1 g (0.29 mole) of 8-chloro-5-nitroquinaldine.
