Nitric Acid → 4-Cyclohexyl-2-nitrophenol

Participants

Reaction Steps

To a stirred mixture of 50 ml of water, 50 ml of ether and 10.0 g of 4-cyclohexylphenol, was added dropwise 12.6 ml of 60% nitric acid while cooling with ice. The temperature of the mixture was raised to room temperature and the reaction was carried out for a day. After 500 ml of water was added, the reaction mixture was extracted with 500 ml of ethyl acetate, washed with water and a brine successively and dried with anhydrous sodium sulfate. The drying agent was filtered off and the solvent was distilled away. The residue was purified by subjecting to silica-gel column-chromatography [eluent:chloroform] to give 6.92 g of 4-cyclohexyl-2-nitrophenol.
