1 g (0.1 mole) of 2-acetoxy-6-naphthoic acid, 0.1 g of N,N-dimethylformamide and 185 g of tetrahydrofuran were fed into. 300 ml-glass container. To this mixture, 23.9 g of thionyl chloride was added dropwise at room temperature under stirring. Then, the reaction was heated to 50° C. and kept at this temperature for 30 minutes. From the resulting mixture, tetrahydrofuran and the excess thionyl chloride were distilled out using a rotary evaporator to give 24.9 g (0.1 mole) of 2-acetoxy-6-naphthoic acid chloride.
