Procedure
4-(Propoxymethyl)benzoic acid (1.4 g, 7.2 mmol) was mixed with thionyl chloride (1.3 g, 10.9 mmol), pyridine (0.1 ml) and toluene (3 ml), followed by reacting them at 80° C. for 2 hours, and distilling off superfluous thionyl chloride and toluene under reduced pressure, to obtain raw 4-(propoxymethyl) benzoyl chloride.
