Procedure

2,6-di-t-butylphenol (8 g, 39 mmoles) is dissolved in 25 ml of cyclohexane at 10° C. A mixture (1/1) of nitric acid/acetic acid (5 ml) is added dropwise to the reaction medium maintained at this temperature. Then agitation is carried out for 15 minutes at ambient temperature, then the precipitate formed is filtered, followed by rinsing with water and with pentane. The 2,6-di-t-butyl-4-nitrophenol obtained (6.34 g, 65%) is dried in an oven and will be used without other purification in the following stages. Pale yellow powder. Melting point: 167-168° C.
