Reaction Steps

A sulphonitric mixture at 0° C., composed of sulphuric acid (3.8 ml) and nitric acid (1 ml), is added dropwise to a mixture, cooled to 10° C., of 2-chloro-1,4-xylene (1.4 g), acetic acid (17 ml) and 98% sulphuric acid (1 ml). The reaction medium is poured into a water/ice mixture and then filtered. The yellow precipitate is recrystallized from petroleum ether to give the title compound.
