Vorschrift

Sodium sulfite (4.75 g, 37.68 mmol) was added to a suspension of 1-bromo-4-(2-bromo-ethyl)-benzene (5.00 g, 18.94 mmol) in water (60 mL). The reaction mixture was heated at 105-107° C. for 18 hours and then cooled to −5° C. The formed precipitate was removed by filtration, washed with water (50 mL) and dried under vacuum to give 4.33 g (86% yield) of the title compound.
