実験手順

To a solution of 1-(3,4-dihydroisoquinolin-2(1H)-yl)-3-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)propan-2-ol (250 mg, 0.61 mmol) in Dioxane (3 mL) was added 2-bromo-4-chloro-1-methoxybenzene (135 mg, 0.61 mmol), 2N K2CO3 (1 mL, 2 mmol) and PdCl2(dppf)2 (20 mg, 0.025 mmol). The reaction mixture was heated at 120° C. under microwave conditions for 30 minutes before being concentrated to remove the solvents. The residue was dissolved in ethyl acetate, washed with water and the separated organic layer was dried and concentrated to yield a crude product which was purified by HPLC separation to give the title compound (102 mg, 39.5%). 1HNMR (CH3OD, 400 MHz) δ: 7.36-7.28 (m, 7H), 7.10-7.02 (m, 3H), 6.98-6.90 (m, 1H), 4.69-4.48 (m, 4H), 4.12-4.03 (m, 2H), 3.78 (s, 3H), 3.70-3.64 (m, 1H), 3.52-3.42 (m, 2H), 3.29-3.18 (m, 2H). LCMS (m/z): 424.2 [M+H]+
