Procedure

To a solution of (4-chloro-benzyl)-ethyl-piperidin-4-yl-amine hydrochloride (0.200 g, 0.83 mmol) in acetonitrile/water (8:2) (8 mL) was added K2CO3 (0.476 g, 3.4 mmol) and 2-[5-(3-bromo-propylidene)-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yl]-propan-2-ol (0.282 g, 7.5 mmol). The solution was allowed to stir at room temperature for 48 h. The reaction was concentrated and partitioned between EtOAc/H2O, extracted with EtOAc (3×). The organics were collected, dried over MgSO4, filtered and evaporated in vacuo, then purified by Biotage flash chromatography (5% methanol/95% methylene chloride to 10% methanol/90% methylene chloride) to yield the title compound (0.240 g, 60%). 1H-NMR (CDCl3): δ 0.988 (t, 3H), 1.57 (s, 6H), 1.67 (d, 2H), 1.85 (t, 2H), 2.32-2.46 (m, 5H), 2.51 (q, 2H), 2.84 (d, 2H), 3.47 (s, 2H), 3.56 (s, 2H), 5.29 (bs, 2H), 6.07 (t, 1H), 6.80 (d, 1H), 7.21-7.28 (m, 6H), 7.42 (s, 1H), 7.56 (d, 1H), 8.48 (d, 1H). ESI-MS m/z: 546 (M+1), retention time 1.87.
