실험 절차

A solution of hydroxylamine-O-sulfonic acid (2) (2 g, 1 equiv.), water (10 mL) and isoquinoline (1) (6.3 mL, 3 equiv.) was heated at 90° C. for 2-3 h. Potassium carbonate (2.44 g, 1 equiv.) was added, and the water was evaporated. Ethanol (20-30 mL) was added to the solid residue, and insoluble potassium sulfate was filtered out. Hydroiodic acid (57%-67%, 1.34 mL, 1 equiv.) was added to the filtrate, and the resulting solution was placed in a freezer. The precipitate was filtered out, washed with ethanol, and dried in vacuo. Isolated products were used as such in further reactions. Yield of the product was 1.78 g.
