Water → 2-[3-(4-Fluorophenyl)-propyl]-6-allyloxy-1-oxo-1,2,3,4-tetrahydroisoquinoline

Participants

Reaction Steps

To a solution of 6-allyloxy-1-oxo-1,2,3,4-tetrahydroisoquinoline (10.6 g, 52 mmol) and 1-bromo-3-(4-fluorophenyl)-propane (17 g, 78 mmol) and KI (430 mg, 2.6 mmol) in dimethyl formamide (DMF) (125 mL) is added NaH (3.1 g, 78 mmol). After 4 hours the reaction mixture is poured into H2O (500 mL) and the resulting suspension is extracted with EtOAc (3×300 mL). The combined organic extracts are washed with H2O (5×200 mL), saturated NaCl solution (2×200 mL), dried over MgSO4 and concentrated in vacuo. The residue is chromatographed (silica gel, 1:1 EtOAc/hexane) to yield 2-[3-(4-fluorophenyl)-propyl]-6-allyloxy-1-oxo-1,2,3,4-tetrahydroisoquinoline as a brown oil.
