الإجراء التجريبي

To a solution of 6-bromo-1-oxo-1,2,3,4-tetrahydroisoquinoline (2.82 g, 12.5 mmol) in DMF (80 ml) is added 1-bromo-3-phenylpropane (2.89 ml, 18.75 mmol), KI (200 mg, 1.25 mmol) and NaH (600 mg, 25 mmol). The reaction mixture is stirred for 3 hours and subsequently poured into H2O (300 ml). The resulting emulsion is extracted with EtOAc (2×150 mL) and the organic phase washed with 2N HCl (1×200 mL), H2O (1×200 mL), saturated NaHCO3 solution (1×200 mL), saturated NaCl solution (2×200 mL), dried over MgSO4 and concentrated in vacuo. The residue is chromatographed (silica gel, 9:1 hexane/EtOAc) to give 2-(3-phenylpropyl)-6-bromo-1-oxo-1,2,3,4-tetrahydroisoquinoline.
