Procedure

Dissolve N-methyl-5-(2-methylacryloyl)-N-propyl-isophthalamic acid methyl ester (50 mg, 0.16 mmol) in methanol (3 mL). Add 2 N NaOH (0.12 mL) and stir overnight at room temperature. Add 2 N NaOH (0.05 mL ) and stir for an additional 3 h. Acidify the mixture to about pH=6 using DOWEX® 50WX2-100 ion exchange resin and filter. Concentrate filtrate to give the title compound which is used in the next step without further purification.
