Reaction Steps
A solution of 1 g (6 mmole) of 2,6-dimethyl-4-nitrophenol in 20 ml of ethanol is placed under 1.5 bar of hydrogen in the presence, of 10% Pd/C for 1 hour. The Pd/C is eliminated by filtration on celite and the filtrate is concentrated under reduced pressure. The evaporation residue crystallizes spontaneously, it is washed twice with 50 ml of heptane and dried overnight under vacuum. A cream coloured solid is obtained with a yield of 86%.
