Procedure

To a solution of 3-[(4-chloro-benzyl)-pyrrolidin-3-yl-amino]-propionic acid methyl ester (0.06 g, 0.2 mmol) in acetonitrile:water (3:1) was added potassium carbonate (0.056 g, 0.4 mmol) and (E)-2-[5-(3-bromo-propylidene)-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yl]-propan-2-ol (0.065 g, 0.17 mmol) and reaction 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 by flash chromatography on silica using ethyl acetate/methanol (5%). 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; 2H, s), 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: 590 (M+1), UV retention time: 1.51 min.
