实验步骤: To a solution of 1-(4-chloro-2-methyl-phenyl)-piperazine (0.13 g, 0.6 mmol) in isopropanol (6.0 mL) was added 2,6-lutidine (95 uL, 0.802 mmol) and catalytic potassium iodide. This mixture was heated to 80° C., and treated with 2-[5-(3-Bromo-propylidene)-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yl]-propan-2-ol (0.15 g, 0.4 mmol), added in portions over 2 h. The solution was then stirred at 80° C. for an additional 12h. The reaction mixture was concentrated in vacuo, then purified by flash chromatography on silica gel (gradient elution from 95% ethyl acetate/5% methanol to 90% ethyl acetate/10% methanol) to yield the title compound (0.11 g, 54%). 1H-NMR (DMSO) δ: 1.45 (6H, s), 2.30-2.65 (8H, m), 2.75-2.85 (4H, m), 3.30 (3H, d), 5.30 (2H, br s), 6.20 (1H, t), 6.75 (1H, d), 7.00-7.47 (6H, m), 7.80 (1H, dd), 8.50 (1H, dd). ESI-MS m/z: 504 (M+1), UV retention time: 1.65 min. added in portions over 2 h The reaction mixture was concentrated in vacuo purified by flash chromatography on silica gel (gradient elution from 95% ethyl acetate/5% methanol to 90% ethyl acetate/10% methanol)
