Reaction Steps

A mixture of dimethyl 3-aminoisophthalate 25.3 g (121 mmol), methanesulfonyl chloride 10 mL (130 mmol) and pyridine (50 mL) was stirred at 50° C. for 4 hours. The reaction solution was poured into a 0.5 N hydrochloric acid (300 mL), and the precipitated solid was collected by filtering, washed with 0.5 N hydrochloric acid and dried under vacuum to give 34.8 g (121 mmol) of the title compound (yield: 100%).
