70% | With triethylamine; In tetrahydrofuran; for 8h;Reflux; | To a solution of hydrazonyl halide i (5 mmol) and 6,7-dimethoxy-3,4-dihydroisoquinoline iii (5 mmo) in tetrahydrofuran (THF) (40 ml) was added triethylamine (TEA) (1.4 ml, 10 mmol) at room temperature. The reaction mixture was refluxed for 8 h. The mixture was then poured on water and extracted with ethyl acetate. The organic layer was collected, dried over anhydrous sodium sulfate and then filtered. The solvent was evaporated under reduced pressure. The solid product was collected and crystallized from ethanol. Yield: (70%) as an orange solid (from ethanol); m.p 130-132 C. IR (KBr, cm-1): 1660 (CO); 1H NMR (300 MHz, DMSO-d6): δ, ppm: 2.5 (s, 3H, CH3), 2.7 (m, 2H, CH2), 3.6 (s, 3H, OMe), 3.7 (s, 3H, OMe), 4.0 (m, 2H, CH2), 6.5 (s, 1H, H10b), 6.6 (s, 1H, H7), 6.7 (s, 1H, H10) 6.9-7.4 (m, 5H, Ph-H) MS (EI): m/z = 351 (M+). Anal. Calcd. for C20H21N3O3 (351.41): C, 68.36; H, 6.02; N, 11.96. Found: C, 68.56; H, 6.14; N, 11.88. |
