Abstract
2-(2-Fluoro-4-nitroanilinoethyl)benzaldehyde, C 15 H 13 -FN 2 O 3 , exists as the aldehyde form with essentially planar and parallel benzaldehyde and nitroaniline fragments, which are linked through an ethylene bridge joining the aniline N atom and an ortho-C atom of the benzaldehyde fragment. N-(2-Fluoro-4-nitrophenyl)-1-methoxy-1,2,3,4-tetrahydroisoquinoline, C 16 H 15 FN 2 O 3 , obtained as a methanolysis product on attempted recrystallization of 2-(2-fluoro-4-nitroanilinoethyl)benzaldehyde from methanol solution, consists of essentially planar nitrobenzene and non-planar tetrahydroquinoline fragments, which are linked directly through the para-C atom of the former and the endocyclic N atom of the latter.
