Reaction Steps
Dissolve (S)-2-sec-butylamino-6-cyano-isonicotinic acid methyl ester (250 mg, 0.93 mmol) in methanol (3 mL). Slowly add 2 N NaOH (1.5 mL) and stir overnight at room temperature. Acidify to about pH=6 with 5 N HCl and concentrate. Dilute with ethyl acetate (20 mL) and wash the organic layer with saturated aqueous sodium chloride, dry (magnesium sulfate) and concentrate to give the title compound.
