Reaction Steps

Thionyl chloride (36.0 g, 302 mmol) was added to a suspension of 4-iodobenzoic acid (50.0 g, 202 mmol) in anhydrous DCM (300 ml) followed by a few drops of DMF and the reaction mixture was stirred overnight at r.t. Upon completion, reaction flask was concentrated under reduced pressure to yield 51.6 g (96.0% yield) of crude 4-iodobenzoyl chloride that was used in the next step without further purification.
