N-Acetyl-p, m or o-nitro-phenylethylamines and (HCHO)n were treated in 60% H2SO4/HOAc, via α-amidoalkylation to give 2-acetyl-mono(5, 6, 7 or 8)-nitro-1,2,3,4-tetrahydro-isoquinolines.Additionally, some interesting phenomena were observed when the comparison between 2-acetyl-5, 6, 7 or 8-nitro-1,2,3,4-tetrahydroisoquinolines and 2-alkylsulfonyl-5 , 6 or 7- nitro-1,2,3,4-tetrahydroisoquinolines was made.
