实验步骤: Light yellow solid. MS (ESI): 513.3 (MH+). This example was prepared in analogy to example 1 step C) to D) from 4-(2-methoxy-ethyl)-piperidine-4-carboxylic acid ethyl ester (example 1 step B)), 2-trifluoromethoxy-benzenesulfonyl chloride and 4-(2-methoxy-ethyl)-phenylamine.

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2 g (13.2 mmol) of 4-(2-methoxy-ethyl)-phenylamine (Example 42b) and 1.85 g (13.9 mmol) of N-chlorosuccinimide (Aldrich, Buchs, Switzerland) in 26 ml of isopropanol are stirred at rt for 30 min. The reaction mixture is evaporated to dryness and the residue is taken in EtOAc. The organic layers is washed with sat. aqueous NaHCO3 (2×), dried over MgSO4, filtered and evaporated. The residue is purified by flash chromatography on silica gel (hexane-EtOAc 5:1 to 2:1) to provide the title compound as an oil. ES-MS: 186 (M+H)+; analytical HPLC: tret=2.42 minutes (Grad 1). The reaction mixture is evaporated to dryness The organic layers is washed with sat. aqueous NaHCO3 (2×) dried over MgSO4 filtered evaporated The residue is purified by flash chromatography on silica gel (hexane-EtOAc 5:1 to 2:1)

实验步骤: Following general procedure A2 except using iso-propanol as a solvent, 4-chloro-2-(3-chlorophenyl)-6,7-dihydro-5H-cyclopenta[b]pyridine hydrochloride (0.107 g, 0.35 mmol) was reacted with 4-(2-methoxyethyl)aniline (0.108 g, 0.71 mmol), followed by formation of the hydrochloride salt to afford the title compound (0.094 g, 64%) as a white solid. MW=415.36. 1H NMR (DMSO-d6, 500 MHz) δ 14.03 (s, 1H), 9.75 (s, 1H), 7.89 (t, J=1.9 Hz, 1H), 7.71-7.67 (m, 2H), 7.59 (t, J=7.9 Hz, 1H), 7.36-7.32 (m, 4H), 6.99 (s, 1H), 3.57 (t, J=6.8 Hz, 2H), 3.25 (s, 3H), 3.15 (t, J=7.5 Hz, 2H), 2.91 (t, J=7.2 Hz, 2H), 2.85 (t, J=6.8 Hz, 2H), 2.24 (quin, J=7.5 Hz, 2H); APCI MS m/z 379 [M+H]+.

实验步骤: A mixture of 2-chloro-4-(3-chlorophenyl)-6-ethyl-1,3,5-triazine (0.105 g, 0.41 mmol) and 4-(2-methoxyethyl)aniline (0.075 g, 0.49 mmol) were suspended in acetic acid (1 mL) and the mixture was heated at 75° C. for 3 h. After this time, the reaction was cooled, diluted with saturated aqueous sodium bicarbonate, and extracted with ethyl acetate. The combined organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by column chromatography (silica, hexanes/ethyl acetate) to afford the title compound (0.094 g, 62%) as a white solid. MW=368.86. 1H NMR (DMSO-d6, 500 MHz) δ 10.21 (s, 1H), 8.41-8.30 (m, 2H), 7.72-7.68 (m, 3H), 7.61 (t, J=7.5 Hz, 1H), 7.27-7.19 (m, 2H), 3.54 (t, J=7.0 Hz, 2H), 3.25 (s, 3H), 2.80-2.75 (m, 4H), 1.32 (t, J=7.5 Hz, 3H); APCI MS m/z 369 [M+H]+. After this time, the reaction was cooled extracted with ethyl acetate The combined organic layer was dried over anhydrous sodium sulfate filtered the filtrate was concentrated The residue was purified by column chromatography (silica, hexanes/ethyl acetate)
