実験手順
Using the same reaction conditions and methods of isolation N-hydroxyethyl-2,3-dichlorobenzylamine hydrobromide (2.0 g, 6.0 mm) was reacted in a melt of 5 g (37.5 mm) of aluminum chloride-0.3 g (5.6 mm) of ammonium chloride to give 1.19 g (75.3%) of 7,8-dichloro-1,2,3,4-tetrahydroisoquinoline hydrochloride which was 95.1% pure by high pressure liquid chromatography.
