Reaction Steps
A solution of 3.7 g (20.4 mmol) N-methyl-5-methoxy-2-nitroaniline in 700 ml ethanol was added 7.4 ml 4N hydrochloric acid, and then hydrogenated at atm. pressure by using 5% Pd-C (0.5 g) as a catalyst. The reaction mixture was filtered and evaporated in vacuo to give 2-amino-5-methoxy-N-methylaniline as crystals.
