Reaction Steps

A mixture formed of 9-benzyl-9,10-diazatricyclo[4.2.1.12,5]decane prepared in Example 2.1 (2.19 mmoles), 4-[chloro-(3-methoxyphenyl)methyl]-N,N-diethylbenzamide obtained in Example 3.1 (1.5 equivalents), anhydrous potassium carbonate (3 equivalents) and acetonitrile (20 ml), is heated at reflux for 3 days. At the end the mixture was filtered under vacuum and the liquid phase recovered. The solvent was evaporated under vacuum and the residual oil purified by flash chromatography. The eluent was ligroin/ethyl acetate 7/3 (v/v). The compound 4-[(10-benzyl-9,10-diazatricyclo-[4.2.1.12,5]dec-9-yl)-(3-methoxyphenyl)methyl]-N,N-diethylbenzamide was obtained. Yield: 52%. IR (nujol) (λ=cm−1) 1680 (C═O); 1H-NMR (CDCl3) δ 1.00-1.30 (m, 6H); 1.60-2.20 (m, 8H); 2.75-2.85 (m, 4H); 3.20-3.36 (m, 2H); 3.37 (s, 2H); 3.40-3.60 (m, 2H); 3.80 (s, 3H); 4.28 (s, 1H); 6.70-6.80 (m, 1H); 7.00-7.40 (m, 10H); 7.55 (d, 2H, J=8.4 Hz).
