Reaction Steps
14.7 g (82.5 mmol) of 2,6-diethyl-4-methylbenzyl alcohol in 150 ml of hydrobromic acid are stirred at 100° C. for 4 h. After cooling, the mixture is extracted with dichloromethane and the extract is washed with water, dried (magnesium sulphate) and concentrated using a rotary evaporator. Distillation (110° C. bath temperature, 0.3 mbar) gives 17.82 g (89%) of 2,6-diethyl-4-methylbenzyl bromide as a colourless oil. 1H-NMR (400 MHz, CDCl3): δ=1.28 (t, 6H), 2.30 (s, 3H), 2.73 (q, 4H), 4.61 (s, 2H), 6.90 (s,
