Potassium Iodide → 2-(5-{3-[4-(4-Chloro-phenyl)-3-methyl-piperazin-1-yl]-propylidene}-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yl)-propan-2-ol

Reaction Steps

A solution of 2-[5-(3-Bromo-propylidene)-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yl]-propan-2-ol (0.24 g, 0.64 mmol) in isopropanol (5 mL) was treated with 1-(4-Chloro-phenyl)-2-methyl-piperazine (0.25 g, 1.2 mmol) and catalytic potassium iodide. The solution was stirred at 80° C. for 5 hr, and evaporated in vacuo. The residue was purified by silica gel chromatography (ethyl acetate→87:10:3 ethyl acetate/methanol/triethylamine) to yield 0.22 g (69%) of the title compound, 1H-NMR (CDCl3) δ: 1.00 (3H, m), 1.60 (6H, s), 2.20–2.70 (8H, m), 3.10 (2H, m), 3.75 (1H, m), 5.30 (2H, brs), 6.12 (1H, t), 6.87(4H, d), 7.18–7.32 (3H, m), 7.45 (1H, s), 7.70 (1H, d), 8.55 (1H, d).
