Add a suspension of potassium peroxymonosulfate (35.6 g, 57.7 mmol) in water (80 mL) to a cooled solution of 2-chloro-6-propylsulfanyl-isonicotinic acid methyl ester (4.71 g, 19.2 mmol) in methanol (40 mL) and THF (40 mL). Stir the mixture at room temperature for 3 days. Dilute the mixture with water and extract with dichloromethane (3×100 mL).
