Reaction Steps

Pyridine hydrochloride salt (3.6 g) was added to 1-butyl-3-methoxypyridine-2-thione (2-034-03) (1.4 g), and the reaction mixture was stirred at 190° C. for 40 min. To the reaction mixture were added water and ethyl acetate, and the organic layer was separated, and the organic layer was extracted three times with ethyl acetate. The combined organic layers were washed with water and brine, dried over anhydrous magnesium sulfate, and evaporated under reduced pressure to give 1-butyl-3-hydroxypyridine-2-thione (2-034-04) (1.02 g, 78%) as an oil.
