実験手順

A mixture of 2,3,6,7-tetrahydro-N-propyl-1H,5H-benzo(ij)quinolizin-2-amine (2.33 g, 0.01 tool), propyl iodide (5.16 g, 0.03 tool) and anhydrous potassium carbonate (3 g, 0.02 tool) in dimethylformamide (75 mL) was stirred for 5 hours at 90° C. At this time additional propyl iodide (1.72 g, 0.01 mol) and potassium carbonate (0.5 g, 0.0036 mol) were added and the reaction was continued for an additional 2 hours. The reaction was cooled, filtered to remove inorganic material, and the solvent was removed under reduced pressure. The product was partitioned between ethyl acetate (800 mL) and 4N sodium hydroxide (20 mL, 0.08 mol), the organic layer concentrated, filtered, and chromatographed on silica gel in 5-30% ethyl acetate:hexane to give 2.19 g of 2,3,6,7-tetrahydro-N,N-dipropyl-1H,5H-benzo(ij)quinolizin-2-amine.
