Procedure
Treat a solution of 5-acetyl-N-methyl-N-propyl-isophthalamic acid ethyl ester (196 mg, 0.67 mmol) in ethanol (7 mL) at room temperature with 2 N NaOH (0.5 mL, 1.0 mmol) for 12 h. Acidify to about pH=3 using 1 N HCl. Extract with ethyl acetate (50 mL), dry (magnesium sulfate) and concentrate to give the title compound (179 mg, 95%).
