実験手順

In a 100 ml roundbottom flask equipped with magnetical stirring, thermometer and addition funnel, 5,6,7,12-tetrahydrodibenzo[b,g]azocine (2.1 g, 0.01 mol, prepared in a similar way as described in Chem. Pharm. Bull., 26, (1978), 942) was dissolved in dry toluene (60 ml) and ethyl malonyl chloride (2.0 g, 0.013 mol) was slowly added. The reaction mixture was heated at reflux temperature for 2 h and then allowed to cool to room temperature. Under stirring, 0.2N NaOH (5 ml) and water (60 ml) were added. More toluene was added (100 ml) and the phases were separated. The organic phase was washed with water (3×75 ml) and brine (75 ml). After drying (MgSO4), the organic phase was evaporated in vacuo affording 3.1 g (95%) of 3-(6,7-dihydro-5H-dibenzo[b,g]azocin-12-yl)-3-oxopropionic acid ethyl ester as an oil.
