Procedure

Chill a solution of (S)-2-sec-butylamino-6-methanesulfonyl-isonicotinic acid methyl ester (1.02 g, 3.57 mmol) in THF (10 mL) in an ice bath. Add 1 N lithium hydroxide (5.4 mL, 5.4 mmol) and stir the solution at room temperature for 3 h. Add 1 N HCl until about pH=2. Concentrate and partition the residue between ethyl acetate and water. Separate the layers and extract the aqueous layer with ethyl acetate (2×30 mL). Wash the combined extract with saturated aqueous sodium chloride, dry (magnesium sulfate) and concentrate to give the title compound.
