Procedure

Dissolve (S)-2-sec-butylamino-6-(cyclopropanesulfonyl-methylamino)-isonicotinic acid methyl ester (600 mg, 1.97 mmol) in methanol (18 mL). Slowly add 2 N NaOH (3 mL) and stir overnight at room temperature. Acidify the mixture to about pH=6 with 5 N HCl and concentrate. Dilute with ethyl acetate (30 mL) and wash the organic layer with saturated aqueous sodium chloride solution, dry (magnesium sulfate) and concentrate to give the title compound.
