Participants

Reaction Steps

To a solution of 3,5,6-trimethyl-2-(2-methyl-2-propenyl)-4-phenylaminophenol (1.40 g, 4.98 mmol) in methanol (30 ml) was added conc. hydrochloric acid (10 ml) with ice-cooling and the mixture was heated with reflux in an argon atmosphere. The reaction mixture was cooled, neutralized with an aqueous sodium bicarbonate solution and extracted with ethyl acetate. The extract was washed with a saturated saline solution and concentrated. The residue was recrystallized from isopropyl ether to obtain the desired compound (0.97 g, yield: 69.3%), m.p. 148°-150° C.
