YieldReaction ConditionsOperation in experiment
Preparation 153-(1-Methylpiperidin-4-yl)-propylamine(A). Preparation of 3-(1-methylpiperidin-4-yl)-propan-1-ol; Formalin (6.33 g, 211 mmol) is added to a stirred solution of 3-(piperidin-4-yl)-propan-1-ol (3.02 g, 21.1 mmol) in acetonitrile (30 mL) at ambient temperature. The solution is allowed to stir for 20 minutes. Sodium cyanoborohydride (3.31 g, 52.7 mmol) and acetic acid (3 mL) are sequentially added to the reaction mixture and the resultant mixture is stirred for another 2 hours. After concentration, the crude product is dissolved in dichloromethane (150 mL), washed with saturated aqueous NaHCO3 (60 mL.x.2), dried and concentrated. The crude product is subjected to chromatography on silica gel and eluted with 2 M NH3/CH3OH in dichloromethane 0-15percent to give the title compound as an oil (2.70 g).
With hydrogen;5% rhodium-on-charcoal; In water; at 20 - 50℃; under 15514.9 Torr; Example 3 1-Methyl-4-Piperidinepropanol An Argonaut reaction vessel was charged with 4-pyridinepropanol (500.0 mg, 3.49 mmol) and 5percent Rh/C (62percent wet, 300.0 mg) in water (4.00 g). The resultant slurry was stirred at 500 RPM and the unit was pressurized with 300 psi of hydrogen. The resultant mixture was heated at 50° C. for about 4-4.5 h, during which time the hydrogen uptake ceased. The resultant mixture was then cooled to room temperature and a 37percent formaldehyde solution (340.0 mg, 4.19 mmol) was added in a single portion. The Argonaut vessel was sealed and the resultant slurry was stirred at 500 RPM, the unit was repressurized with 300 psi of hydrogen, and heated to 50° C. Hydrogen uptake ceased in about 1.2-1.5 h to yield the title compound, which was used in the next step without further purification or isolation.
