Procedure

The nitro-tetrahydroisoquinoline of formula (IV) in which XA is hydrogen may be prepared by hydrolysis of 2-trifluoroacetyl-7-nitro-tetrahydroisoquinoline obtained by reaction of an N-(nitrophenyl)ethyl-trifluoroacetamide and paraformaldehyde in acidic conditions using the procedure of Stokker, Tet. Lett., 1996, 37, 5453. N-(nitrophenyl)ethyl-trifluoroacetamides can be prepared from readily available materials by reaction of trifluoracetic anhydride with lutidine and nitrophenethylamine hydrochloride, as illustrated in the Descriptions below.
