| Conditions | Yield |
| With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; triethylamine In dichloromethane at 20℃; for 17h; Experimental Procedure 1-(1-(3,4-Dimethoxybenzyl)-6,7-dimethoxy-3,4-dihydroisoquinolin-2(1H)-yl)-2-(3,4-dimethoxyphenyl)ethanone (7) A mixture of 6•HCl (5.7 g, 15 mmol), homoveratric acid 10 (2.94 g, 15 mmol), HOBt (2.28 g, 16.8 mmol),EDC (3 mL, 16.8 mmol) and Et3N (6.3 mL, 45 mmol) in CH2Cl2 (300 mL) was stirred at room temperaturefor 17 h. The mixture was diluted with CH2Cl2 (100 mL) and was washed with 10% HCl (30 mL x 2), satdNaHCO3 (30 mL) and brine (30 mL), dried over Na2SO4, filtrated and evaporated to afford yellow solids.Recrystallization from EtOH (135 mL) gave amide 7 (6.96 g, 89%) as yellow solids of mp 148-150 °C.1H NMR (the ratio of rotamer is 66/34): 2.49-2.61 (1.32H, m), 2.70 (0.34H, m), 2.92 (0.34H, m), 2.93(0.66H, dd, J = 8.0, 13.2), 2.98 (0.34H, dd, J = 5.2, 13.7), 3.02 (0.34H, d, J = 16.0), 3.07 (0.34H, dd, J = 9.2,13.7), 3.10 (0.66H, dd, J = 5.8, 13.2), 3.19 (0.34H, m), 3.24 (0.34H, d, J = 16.0), 3.38 (0.66H, m), 3.61(1.98H, s), 3.67 (1.02H, s), 3.68-3.73 (1.98H, m), 3.75 (1.98H, s), 3.80 (1.98H, s), 3.83-3.84 (6H, m), 3.86(1.02H, s), 3.87 (3H, s), 3.88 (1.02H, s), 4.82 (0.34H, m), 4.92 (0.34H, dd, J = 5.2, 9.2), 5.67 (0.66H, dd, J= 5.8, 8.0), 6.18 (0.66H, s), 6.39 (0.34H, s), 6.43-6.45 (0.68H, m), 6.15-6.52 (1.32H, m), 6.62-6.80 (4.66H,m), 6.84 (0.34 H, d, J = 8.6). 13C NMR: 27.9 (CH2), 28.3 (CH2), 35.2 (CH2), 39.6 (CH2), 41.1 (CH2), 41.2(CH2), 41.8 (CH2), 42.4 (CH), 54.0 (CH), 56.6 (CH3), 55.8 (CH3), 55.93 (CH3), 55.96 (CH3), 55.99 (CH3), 56.1 (CH3), 58.6 (CH), 110.1 (CH), 110.82 (CH), 110.89 (CH), 110.93 (CH), 111.2 (CH), 111.4 (CH), 111.5(CH), 111.6 (CH), 111.8 (CH), 111.9 (CH), 112.8 (CH), 112.9 (CH), 120.8 (CH), 120.9 (CH), 121.9 (CH),122.1 (CH), 125.6 (C), 126.7 (C), 127.5 (C), 127.7 (C), 128.0 (C), 128.3 (C), 130.5 (C), 130.7 (C), 147.0(C), 147.4 (C), 147.69 (C), 147.72 (C), 147.9 (C), 148.2 (C), 148.3 (C), 148.9 (C), 145.1 (C), 170.1 (C),170.4 (C).
