The benzoyl thiourea is added to a solution of potassium carbonate (1.4 g.) in water (80 ml.) at 60°. The solution is maintained at this temperature for one hour, concentrated to low bulk and acidified with hydrochloric acid. Benzoic acid is removed by filtration and the filtrate is basified with potassium carbonate and concentrated under reduced pressure. Following extraction with isopropyl alcohol and concentration, the product is N-[2-(2-pyridylmethylthio)ethyl]thiourea.
