Upon complete addition the mixture was allowed to warm to room temperature, then heated at reflux for 45 minutes (gas evolution observed). Upon cooling the thionyl chloride was removed in vacuo. The residue was partitioned between dichloromethane and aqueous sodium hydrogen carbonate. The aqueous phase was further extracted with dichloromethane (x2). The combined extracts were dried (Na2SO4), filtered and evaporated to give the title chloride (570 mg), as an oil. This material was used without further purification.
