Abstract
3,4 - Dimethyl - 8 - nitroquinoline is prepared by heating ortho-nitroaniline with methyl isopropenyl ketone (or an exemplified list of precursors thereof which generate said ketone when treated with mineral acid and water) at a temperature ranging from 110 DEG to 130 DEG C. in a reaction medium essentially consisting of arsenic acid containing from 5 to 40% by weight of sulphuric acid. The desired product is recovered from the reaction mixture by addition of water, distilling off excess methyl isopropenylketone, cooling to 50-60 DEG C., filtering, addition of alkali to a pH of 8.0, washing the precipitated product successively with water and methanol and drying it at 55 DEG C.
