Procedure

To a solution of 2-[(4-chloro-benzyl)-pyrrolidin-3-yl-amino]-ethanol (0.15 g, 0.6 mmol) in acetonitrile:water (4:1) was added potassium carbonate (0.11 g, 0.8 mmol) and (E)-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) and the resulting mixture was stirred at 50° C. for 24 h. The reaction mixture was concentrated in vacuo, diluted with ethyl acetate and dried over sodium sulfate. The crude product was purified on silica. 1H-NMR (CDCl3) δ: 1.40 (6H, s), 1.60 (1H, m), 1.80 (1H, m), 2.10-2.60 (8H, m), 3.20-3.40 (6H, m), 3.50 (2H, m), 5.20 (2H, br, s), 6.15 (1H, t), 6.70 (1H, t), 7.18-7.42 (7H, m), 7.70 (1H, dd), 8.50 (1H, dd). ESI-MS m/z: 548 (M+1), UV retention time: 1.26 min.
