Reaction Steps

To a solution of 4-chloro-2-methoxybenzoic acid (1.0 g, 5.36 mmol) in toluene (10 ml) was added thionyl chloride (2.76 ml, 37.52 mmol) at room temperature under nitrogen atmosphere. The resulting reaction mixture was heated to 80° C. for 1 h. After the completion of the reaction (TLC monitoring), the solvent was evaporated under vacuum and was carried forward as such for the next step.
