Versuchsvorschrift
4-Bromo-3-methoxybenzyl alcohol (21.7 g, 0.1 m) dissolved in toluene (200 ml) containing pyridine (11.8 g, 0.15 m) is stirred at 5° and treated wiih thionyl chloride (23.8 g, 0.2 m). The mixture is stirred, diluted with water and the organic layer washed with dilute hydrochloric acid, dried and concentrated in vacuo to give 4-bromo-3-methoxybenzyl chloride.
