Reaction Steps

2.00 g (11.06 mmol) 4-amino-3-methyl-5-nitrophenol were placed in 50 mL methanol and hydrogenated under a hydrogen atmosphere and with the addition of 1.00 g Pd/C (10%) at 50° C. and a hydrogen pressure of 5 bar until all the hydrogen had been taken up. The catalyst was filtered off and the filtrate was evaporated down i.vac.
