How do you make M nitroaniline from m-dinitrobenzene?
Dissolve 6.7g (0.04 mol) of m-dinitrobenzene in 50 ml of hot methanol in a 250-ml round-bottomed flask and add, with shaking, the previously prepared methanolic solution of sodium hydrogen sulphide. Attach a reflux condenser and boil the mixture for 20 min; ignore any further sodium carbonate which may precipitate.
