Procedure

Dissolve 5-nitro-N,N-dipropyl-isophthalamic acid methyl ester (1.000 g, 3.243 mmol) and lithium hydroxide (0.089 g, 3.730 mmol) in a mixture of THF (3.16 mL), water (1.58 mL) and methanol (1.58 mL). Stir the mixture at room temperature until the starting material is consumed. Concentrate and acidify with 1 N HCl. Extract with ethyl acetate, dry (magnesium sulfate) and concentrate to give the title compound (0.874 g, 92%).
