Reaction Steps
Methanesulfonic acid (0.00732 g, 0.0762 mmol) was added to a methanol solution (2 ml) of N-(pyridin-3-yl)-5-(5,6-dimethoxy-3-methyl-1,4-benzoquinon-2-yl)methyl-2-acetoxybenzamide (0.0327 g, 0.0726 mmol), and the solvent was removed by distillation. The obtained residue was recrystallized from a mixed solvent of methanol, hexane and toluene (1:2:0.2) to obtain the titled compound (0.030 g, 0.0595 mmol, 82%).
