실험 절차

5,6,7,8-Tetrahydroquinoline (20 g) was added quickly to sodamide (17.6 g) in liquid ammonia (250 ml) to give a dark red coloured solution. 3-Chloropropylamine hydrochloride (28.9 g) was added in portions over four hours when loss of colour was permanent after which the reaction was stirred for a further 2 hours and then quenched with ammonium chloride (20 g). The liquid ammonia was allowed to evaporate and the residues were partitioned between chloroform and water. The pH was lowered to 6 and the chloroform layer was discarded. The aqueous layer was basified (pH 12-14), and extracted with chloroform, the chloroform extracts were dried, combined, evaporated and the residue was vacuum distilled to give 3-(5,6,7,8-tetrahydroquinol-8-yl) propylamine (7.58 g), b.p. 92°-94° C. at 0.1 mm Hg.
