Procedure

Dissolve sodium sulfite (1.7 g, 13.51 mmol) and sodium bicarbonate (1.2 g, 14.19 mmol) in water (10 mL). Add 5-chlorosulfonyl-isophthalic acid dimethyl ester (2.0 g, 6.76 mmol) and ethanol (2 mL). Heat to 50° C. for 2 h, concentrate and dry the solid. Add DMF (40 mL) and iodomethane (4.56 g, 32 mmol) and stir at room temperature for 3 h. Dilute with ethyl acetate, wash with 10% aqueous potassium carbonate, 1 N lithium chloride and saturated aqueous sodium chloride. Dry (magnesium sulfate) and concentrate to give the title compound as a solid.
