Reaction Steps

A solution of 12.5 g of thionyl chloride in 20 ml of chloroform is added dropwise, at RT, to a solution of 14.5 g of 3,5-dichlorobenzyl alcohol in 150 ml of chloroform, followed by heating at 40-50° C. for 8 hours and stirring at RT overnight. The mixture is concentrated under vacuum to give 16 g of the expected product, which is used without further processing.
