Reaction Steps

To a solution of 2-methanesulfonyl-6-methoxy-isonicotinic acid methyl ester (4.3 g, 17.5 mmol) in ethanol (75 mL) was added 2 N aqueous sodium hydroxide (35 mL, 70 mmol). The mixture was warmed at 80° C. for 4 hours and then concentrated in vacuo to remove the ethanol. The remaining aqueous solution was acidified with 1 N aqueous HCl and extracted with ethyl acetate (4×30 mL). The combined organic layers were washed with brine (2×100 mL), dried over sodium sulfate and concentrated to afford 2-methanesulfonyl-6-ethoxy-isonicotinic acid.
