Dissolve the crude ethyl-[butyl-(toluene-4-sulfonyl)-amino]-acetate (10 mmol) in methanol (25 mL) and water (25 mL). Add sodium hydroxide (10 mmol) and stir the reaction at room temperature for 5 hours. Dilute the reaction with water (100 mL) and rinse with methylene chloride. Neutralize the aqueous with 1N hydrochloric acid and extract with methylene chloride (3×75 mL). Combine the organic extracts and rinse with water (100 mL), brine (100 mL), dry over anhydrous sodium sulfate, filter and concentrate under vacuum to provide [butyl-(toluene-4-sulfonyl)-amino]-acetic acid.
