Procedure

Add 1 N lithium hydroxide (2 mL) to a solution of 2-sec-butylamino-6-methanesulfonyloxy-isonicotinic acid methyl ester (235 mg, 0.743 mmol) in THF (15 mL) at 0° C. Warm to room temperature and stir for 12 h. Acidify with 5% aqueous HCl to about pH=3, extract with ethyl acetate, dry (magnesium sulfate), and concentrate to give the title compound.
