Procedure

To a solution of (4-chloro-benzyl)-isopropyl-pyrrolidin-3-yl-amine (0.68 mmol, 1.7 eq) in acetonitrile:water (4:1) was added potassium carbonate (0.8 mmol, 2 eq) and (E)-2-[5-(3-bromo-propylidene)-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yl]-propan-2-ol (0.4 mmol, 1.0 eq) 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 by flash chromatography using ethyl acetate/methanol (5%). 1H-NMR (CDCl3) δ: 0.85 (6H, d), 1.50–1.90 (10H, m), 2.10–2.60 (8H, m), 3.50 (3H, m), 5.30 (2H, br, s), 6.10 (1H, t), 6.80 (1H, dd), 7.10–7.40 (8H, m), 7.50 (1H, d), 8.50 (1H, dd). ESI-MS m/z: 546 (M+1), UV retention time: 1.40 min.
