To the stirred solution of dimethyl 2,6-dichlorobenzene-1,4-dicarboxylate (2 g, 7.6 mmol, Step b) in tetrahydrofuran and water (1:1, 20 mL), sodium hydroxide (304 mg, 7.6 mmol) was added and the reaction mixture was stirred at room temperature for 16 hours. The reaction mixture was concentrated under vacuum and the residue was neutralized using cold hydrochloric acid (1N). The precipitated solid was filtered under suction, washed with hexane and dried to afford 3,5-dichloro-4-(methoxycarbonyl)benzoic acid as an white solid (1.5 g, 85%). 1H NMR (400 MHz, DMSO-d6): delta 7.93 (s, 2H), 3.94 (s, 3H). MS: 247.6 (M-2), 249.6 (M).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Dimethyl 2,6-dichloroterephthalate, its application will become more common.
