Reaction Steps

A 20 mL DMF solution of N-bromosuccinimide (4.07 g, 22.9 mmol) was slowly added to a DMF solution (100 mL) of 2-phenyl-4-tert-butyl-phenol (4.93 g, 21.8 mmol), forming a dark green solution. After stirring in the dark for 48 h, the resultant dark red solution was poured into 500 mL of water, forming a cloudy solution. This was extracted with 95:5 hexane/toluene (3×200 mL), dried over MgSO4, filtered and the solvent removed to give 7 as a thick red oil. Yield: 6.32 g (95%).
