실험 절차

Combine 6-Methoxy-1,2,3,4-tetrahydro-isoquinoline (5.0, 20.5 mmol) and 48% HBr(aq), 20 ml at room temperature. After the reaction refluxes for 24 hours, cool the reaction to room temperature and concentrate under reduced pressure. Triturate with ethyl acetate and filter to afford 5.5 g, 20.5 mmol (99% yield) of the title compound as a tan solid: 1H NMR (500 MHz, DMSO); 2.8-2.9 (2H, m), 3.3-3.4 (2H, m), 4.1 (2H, s), 6.5-6.7 (2H, m), 6.9-7.1 (1H, m), 8.8-9.0 (2H, br s), 9.4-9.5 (1H, s).
