Reaction Steps
Stir a solution of 5-(methyl-propylcarbamoyl)-isophthalic acid 1-ethyl ester 3-isopropyl ester (149 mg, 0.4 mmol) in 0.2 N NaOH in 1:10 water:isopropanol (2.2 mL) overnight. Add 1 N lithium hydroxide (0.44 mL) and stir for 1 h at room temperature. Dilute with water and extract with dichloromethane. Acidify the aqueous with 5 N HCl, extract the aqueous with dichloromethane, dry (magnesium sulfate) and concentrate to give the title compound (79 mg, 56%).
