Participants

Reaction Steps

Add 2 N NaOH (7.0 mL, 14.0 mmol) to a solution of 2-sec-butylamino-6-isopropanesulfonyl-isonicotinic acid methyl ester (1.46 g, 4.65 mmol) in methanol (10 mL) at 0° C. Stir the mixture at room temperature for 3 h and acidify the solution to about pH=2 and concentrate the solvent to one half volume. Partition the residue between ethyl acetate and water, and extract the aqueous layer with ethyl acetate (2×50 mL). Wash the combined organic extracts with saturated aqueous sodium chloride, dry (magnesium sulfate) and concentrate to give the title compound in 90% yield.
