실험 절차

Excess of 2 mol L-1 aqueous sodium hydroxide was added to a solution of 5-(tetrahydropyran-2-yloxy)-2-trifluoroacetyl-1,2,3,4-tetrahydroisoquinoline (Example 3) (4.1 g, 12.4 mmol) in dioxane. The mixture was stirred overnight, diluted with dichloromethane, washed with water and aqueous sodium chloride and evaporated. Yield 2.77 g, 96% 1H NMR (CDCl3, 400 MHz): 7.07 (1H, t, 8.1 Hz), 6.92 (1H, d, 8.3 Hz), 6.66 (1H, d, 7.6 Hz), 5.43 (1H, t, 3.2 Hz), 3.99 (2H, s), 3.76 (1H, m), 3.61 (1H, m), 3.14 (2H, t, 6.1 Hz), 2,73 (2H, m), 1.5-2.1 (6H, m); 13C NMR (CDCl3, 100 MHz): 154.6, 137.2, 126.0, 124.3, 119.1, 111.2, 95.8, 61.9, 48.3, 43.7, 30.5, 25.2, 23.5, 18.9; MS (EI, 70 eV): 233 (M+, 8%), 148 (92%), 132 (23%), 120 (47%), 91 (16%), 85 (100%).
