YieldReaction ConditionsOperation in experiment
0.8 g (13%) With sodium hydroxide; sodium borohydrid; trifluoroborane diethyl ether; In tetrahydrofuran; water; ethyl acetate; toluene; Example 12 (R)-1-(3-(11H-10-Oxa-5-aza-5H-dibenzo[a,d]cyclohepten-5-yl)-1-propyl)-3-piperidinecarboxylic acid hydrochloride In a 500 ml roundbottom flask equipped with magnetical stirring, thermometer and addition funnel <strong>[3433-74-7]5,11-dihydro-10-oxa-5-azadibenzo[a,d]cycloheptene</strong> (4.0 g, 0.02 mol, prepared in a similar way as described in J. Med. Chem., 7, (1964), 609) was dissolved in dry toluene (50 ml) and 3-bromopropionyl chloride (4.2 g, 0.024 mol) was slowly added. The reaction mixture was heated to 95 C. for 30 minutes and then allowed to cool to room temperature. Under stirring 0.2N NaOH (10 ml) was added. More toluene was added (50 ml) and the phases were separated. The organic phase was washed with 0.2N NaOH (3*20 ml) until pH>10, and then with water (3*20 ml) and brine (20 ml). After drying (MgSO4), the organic phase was evaporated in vacuo affording an oil. The product was obtained in quantitative yield and used for further reactions without purification. The above amide (3.5 g, 0.01 mol) was dissolved in dry THF (20 ml) under a nitrogen atmosphere and cooled to 5 C. Sodium borohydride (0.31 g, 0.008 mol) was added followed by slow dropwise addition of boron trifluoride etherate (2.0 ml, 0.016 mol). The reaction mixture was left stirring overnight. Further amounts of sodium borohydride (1.2 g. 0.032 mol) and boron trifluoride etherate (5 ml, 0.040 mol) were supplied, and stirring was continued overnight. Water was added to dissolve precipitated salt, followed by ethyl acetate (100 ml). The phases were separated, and the aqueous phase was extracted with ethyl acetate (2*100 ml). The combined organic extracts were washed with water (4*100 ml) and brine (100 ml). After drying (MgSO4) the solvent was removed by evaporation in vacuo and the crude product was purified by column chromatography on silica gel (200 g) with dichloromethane as eluent. This afforded 0.8 g (13%) of the product, 3-bromo-1-(11H-10-oxa-5-aza-5H-dibenzo[a,d]cyclohepten-5-yl)propane. Rf: 0.62 (SiO2; dichloromethane).
