96% | With 1H-imidazole; iodine; triphenylphosphine; In benzene; at 20℃; for 3h; | Imidazole (1.58 g, 23.2 mmol), triphenylphosphine (6.09 g, 23.2 mmol) and iodine (4.72 g, 18.6 mmol) were added to 1-(tert-butoxycarbonyl)piperidin-3-yl methanol (2.00g, 9.29 mmol) in benzene (50 mL). The mixture was stirred at room temperature for 3 hours. Subsequently, the reactionmixture was filtered through Celite and the solvent was evaporated. Water was added to the residue and the mixture was extracted with ethyl acetate. The extract was washed with brine and was dried over magnesium sulfate, followed by evaporation of the solvent. Purification of the residue by silica gel column chromatography (hexane: ethyl acetate = 20:1 -> 5:1) gave 2.91 g (96%) of the desired compound as a pale yellow oil. 1H NMR (400 MHz, CDCl3) delta 1.19-1.28 (1H, m), 1.40-1.52 (10H, m), 1.61-1.68 (2H, m), 1.91-1.95 (1H, m), 2.54-2.69 (1H, m), 2.79-2.84 (1H, m), 3.08 (2H, d, J = 6.7 Hz), 3.84 (1H, td, J = 13.4, 3.7 Hz), 3.97-4.13 (1H, m).

The solvent is decanted from any insoluble material and is removed under reduced pressure. The residue is filtered through a pad of silica gel using MTBE as eluent to give the title compound as an oil. |

37% | With NaH; In ethyl acetate; N,N-dimethyl-formamide; | EXAMPLE 87 1-(1-Phenethylpiperidin-3-ylmethyl)-3,4-dihydro-1H-quinolin-2-one (130) To a solution of 3,4-dihydro-1H-quinolin-2-one (96 mg, 0.65 mmol) in 1.5 mL of DMF was added NaH (26 mg, 1 eq.). The mixture was stirred at room temperature for 45 min. <strong>[253177-03-6]3-Iodomethylpiperidine-1-carboxylic acid tert-butyl ester</strong> (200 mg, 0.62 mmol) in 0.5 mL of DMF was introduced slowly to the reaction mixture. The reaction was continued for 1 h. at room temperature. The mixture was diluted with 10 mL of EtOAc and washed with aqueous HCl (5%, 5 mL), NaHCO3 (sat., 5 mL), brine (10 mL), and dried over anhydrous sodium sulfate. After the solvent was removed, the remaining oily residue was purified by preparative thin layer chromatography (EtOAc/Hexane, 3:7) to afford 3-(2-oxo-3,4-dihydro-2H-quinolin-1-ylmethyl)piperidine-1-carboxylic acid tert-butyl ester (2) as a colorless oil (80 mg, 37%). |

99% | With potassium carbonate; In N,N-dimethyl-formamide; at 20℃; for 0.5h; | 2-Mercapto-4-phenylthiazole (304mg, 1.54 mmol) and potassium carbonate (261 mg, 1.85 mmol) were added to 1-(tert-butoxycarbonyl)-3-iodomethylpiperidine (500 mg, 1.54 mmol) in N,N-dimethylformamide (5 mL). The mixture was stirred at room temperature for 30 min. Subsequently, water was added and the mixture was extracted with ethyl acetate. The extract was then washed with brine, followed by drying over magnesium sulfate and evaporation of the solvent. Purification of the resulting residue by silica gel column chromatography (hexane: ethyl acetate = 40:1 -> 10:1) gave 598 mg (99%) of the desired compound as a colorless oil. 1H NMR (400 MHz, CDCl3) delta 1.31-1.38 (1H, m), 1.41-1.49 (10H, m), 1.65-1.72 (1H, m), 1.92-2.01 (2H, m), 2.67-3.00 (2H, m), 3.19-3.28 (2H, m), 3.77-3.85 (1H, m), 3.91-4.08 (1H, m), 7.30-7.35 (2H, m), 7.39-7.43 (2H, m), 7.87-7.89 (2H, m).

50% | In an argon atmosphere, a solution of 1.8mol/L lithium diisopropylamide in heptane/tetrahydrofuran/ethylbenzene (1.22 mL, 2.19 mmol), chilled to -78C, was added to 2-[2-(4-chlorophenyl)-4-methylthiazol-5-yl]-2-(trimethylsilylo xy) acetonitrile (669 mg, 1.99 mmol) in tetrahydrofuran (2 mL). The mixture was stirred for 20 min, followed by addition of 1-(tert-butoxycarbonyl)-3-iodomethylpiperidine (647 mg, 1.99 mmol) in tetrahydrofuran (2 mL). The mixture was further stirred for 1 hour as it warmed from -78C to room temperature. 0.5mol/L ice-chilled hydrochloric acid was then added and the mixture was further stirred for 10 min. Subsequently, the mixture was extracted with ethyl acetate and washed sequentially with a saturated aqueous sodium bicarbonate solution and brine. The washed product was dried over magnesium sulfate and the solvent was evaporated. Purification of the resulting residue by silica gel column chromatography (hexane: ethyl acetate = 20: 1 -> 5: 1) gave 429 mg (50%) of the desired compound as a yellow oil. 1H NMR (400 MHz, CDCl3) delta 1.22-1.52 (12H, m), 1.61-1.68 (1H, m), 1.86-1.93 (1H, m), 2.18-2.28 (1H, m), 2.67 (1H, dd, J = 7.3, 15.9 Hz), 2.78 (3H, s), 2.82 (1H, dd, J = 15.9, 6.1 Hz), 2.87-3.10 (1H, m), 3.67-3.97 (2H, m), 7.44 (2H, d, J = 8.6 Hz), 7.92 (2H, d, J = 8.6 Hz).
