A suspension of 5 g. of 3-(p-methoxybenzylthio)-picolinamide in 50 ml. of 20% aqueous sodium hydroxide is refluxed for about 24 hours, then cooled and acidified with dilute hydrochloric acid. Filtering, washing the precipitate with water, drying and recrystallizing from methanol gives 3-(p-methoxybenzylthio)picolinic acid.
