Reaction Steps
3,4-Dichloro-5-methoxybenzoic acid (22.1 g., 0.1 mole) is heated with thionyl chloride (15 g., 0.125 mole) in benzene (100 ml.) until evolution of sulfur dioxide and hydrogen chloride ceases. The benzene and excess thionyl chloride are evaporated and the solid residue is used in the next step.
