Participants

Reaction Steps

To a solution of (5-bromo-2-iodophenyl)methanol (1.4 g, 4.5 mmol) in DCM (20 mL) was added SOCl2 (3.2 g, 26.9 mmol) at 0° C., and the reaction was stirred at rt overnight. The solution was concentrated, and the residue was purified silica gel chromatography (PE) to give 1.2 g (81%) of the title compound as a brown solid.
