反応手順
2-Methyl-3-hydroxy-4-chloromethyl-5-vinylpyridine (20 g.) is suspended in water/methanol (100:25 v/v) and treated with disodium trithiocarbonate (33%) (45 g.). The mixture is stirred at b 50° C. for 4 hours under nitrogen and adjusted to pH 6.2-6.5 with dilute acid. The precipitate is recrystallized from DMF/water to give sodium (2-methyl-3-hydroxy-5-vinyl-4-pyridinyl)methyl trithiocarbonate.
