Versuchsvorschrift
The crude alcohol from above (6.5 g, 22 mmole) was dissolved in 50 ml of dichloromethane, and 2.4 ml (33 mmole) of thionyl chloride was added dropwise at room temperature. The reaction was allowed to stir overnight and the solvent was removed under vacuum. The crude product was redissolved in 50 ml of toluene and the solvent was again removed under vacuum in order to eliminate excess thionyl chloride, providing 6.85 g of crude 4-bromo-3'-methoxybenzhydryl chloride as a dark oil.
