실험 절차

1-Methyl-3,4-dihydroisoquinoline (4.25 g, 29.3 mmol) was dissolved in ice cold concentrated sulfuric acid (15 ml) and to this was added potassium nitrate (3.25 g, 32.2 mmol) portionwise with cooling. The mixture was stirred overnight, poured over ice, basified with concentrated ammonium hydroxide, and the precipitated solid was collected, washed with water and dried: 4.47 g (80%), MS (M+H)+ 191, 1H NMR (D2O), 8.30 (d, 1H), 8.22 (dd, 1H), 7.39 (d, 1H), 3.80-3.62 (m, 2H), 2.92-2.70 (m, 2H), 2.48 (broad s, 3H).
