2-Methyl-6-nitroaniline → 2,3-Diaminotoluene

Participants

Reaction Steps

A solution of 4.56 (30 m mol) of 2-methyl-6-nitroaniline in 150 ml of methanol was hydrogenated at atmospheric pressure over 0.9 g of 5% Pd/C with Ishii's Catalytic Hydrogenation Apparatus with Magnetic Stirrer Model CHA-M. The catalyst was filtered off. The solvent was evaporated, and the residue was crystallized from petroleum ether to give 3.25 g (88.67%) as gray crystals.
