실험 절차

1.8 g (6.26 mmol) of 6,7-dimethoxy-1,2,3,4-tetrahydro-isoquinoline-3-carboxylic acid methyl ester and 3.3 g (37.6 mmol) of MnO2 in toluene/dioxane/THF was heated under reflux overnight. After gravity filtration, the hot filtrate was evaporated to produce 0.4 g (1.62 mmol, 26%) of 6,7-dimethoxy-isoquinoline-3-carboxylic acid methyl ester. LCMS: 248 (M+1)+.
