실험 절차
To a solution of 5-methyl-6-(4-pyridinyl)-2H-1,4-thiazin-3(4H)-one (0.88 g) in methanol (30 ml), p-toluenesulfonic acid monohydrate (0.97 g) was gradually added. The reaction mixture was stirred at room temperature for 30 minutes. Methanol was removed under reduced pressure and the residue was recrystallized from ethanol to give 5-methyl-6-(4-pyridinyl)-2H-1,4-thiazin-3(4H)-one p-toluenesulfonate (1 g, yield 62.5%) as yellow fine needles.
