실험 절차

A mixture of 1 g of 2,6-di-t-butyl-4-methyl phenol, 0.9 g of N-bromosuccinimide and 40 ml of carbon tetrachloride was boiled for 1.5 hours. Succinimide was removed by filtration, and the resulting organic solution was evaporated to give a viscous liquid with the following 1H NMR spectrum (CDCl3, ppm from TMS): 7.05 ppm (s, ArH, 2), 5,15 ppm (s, OH, 1), 4.35 ppm (s, CH2Br, 2) and 1.3 ppm (s, CH3, 18).
