Reaction Steps
To a 500 mL three-necked flask equipped with a mechanical stirrer are added 60 g of 2-nitroaniline and 134.2 g of concentrated hydrochloric acid. After heating to 65° C., 46 g of water is added after which the reactor is cooled to 0° C. Sodium nitrite (74.2 g, 40% aqueous solution) is slowly added to the slurry while maintaining a temperature of 0° C. The diazonium salt solution is filtered to give 290 g of solution which is stored at −15° C. for later use.
