Reaction Steps

15.2 g of 2-methyl-4-nitroaniline were dissolved in 150 ml conc. H2SO4 and heated in a boiling water bath. To this solution 24 g. of paraformaldehyde were added with stirring over a period of 10 minutes. The mixture was stirred an additional hour and was then cooled and poured over 300 g of ice. The precipitate was recrystallized from ethanol water to give 10.1 g of N,2-dimethyl-4-nitroaniline (m.p. 133°-136°C).
