Procedure

Dissolve (S)-2-sec-butylamino-6-(2-oxopropyl)-isonicotinic acid methyl ester (50 mg, 0.19 mmol) in THF (2 mL). Slowly add 1 N lithium hydroxide (0.28 mL) and stir overnight at room temperature. Acidify the mixture to about pH=6 by 5 N HCl and concentrate to near dryness. Dilute with ethyl acetate (10 mL) and wash the organic layer with saturated aqueous sodium chloride. Dry (magnesium sulfate) and concentrate to give the title compound as a solid.
