Reaction Steps

To a solution of 2-[(4-chloro-benzyl)-pyrrolidin-3-yl-amino]-acetamide (0.21 g, 0.8 mmol) in acetonitrile:water (4:1) was added potassium carbonate (0.6 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 by HPLC. 1H-NMR (CDCl3) δ: 1.35 (6H, s), 1.55-1.75 (1H, m), 1.80-2.00 (1H, m), 2.20-2.85 (8H, m), 2.90-3.10 (2H, d), 3.30-3.50 (1H, m), 3.60 (1H, d), 4.80-5.30 (2H, br, s), 6.10 (1H, t), 6.70 (1H, dd), 7.00-7.45 (7H, m), 7.70 (1H, dd), 8.50 (1H, dd). ESI-MS m/z: 562 (M+1), UV retention time: 1.31 min.
