Procedure

2-Chloro-1-[1-(2-methoxy-phenyl)-cyclobutyl]-ethanone (55 mg) in 2 mL acetonitrile was treated with freshly flamed-dried KF on Celite (200 mg) and 3-(4-trifluoromethyl-phenoxymethyl)-piperidine (66 mg, 1.1 equiv). The mixture was stirred overnight, diluted with THF (5 mL), filtered, concentrated in vacuo and purified on silica gel to give the desired 1-[1-(2-methoxy-phenyl)-cyclobutyl]-2-[3-(4-trifluoromethyl-phenoxymethyl)-piperidin-1-yl]-ethanone (32 mg, 30%). Data for this amino ketone: MS 462 (M+1); 1H NMR (300 MHz, CDCl3) partial: δ 6.8-7.6 (m, 8H), 3.85-3.95 (m, 2H, methylene adjacent to aryl ether), 3.09 (s, 2H, methylene adjacent to keto and amine moieties).
