Reaction Steps

4-Bromophenylacetic acid (100 g, 0.465 mol), thionyl chloride (300 mL) and DMF (about 2 mL) are charged to a 1-liter round bottom 3-necked flask equipped with a reflux condenser and a mechanical stirrer. The reaction mixture is heated under nitrogen to 50° C. for 2 hours, using a charcoal scrubber for escaping gases. The thionyl chloride is evaporated and the product, 4-bromophenylacetyl chloride, is put into an addition funnel with benzene (30 mL).
