Versuchsvorschrift
In analogy to the procedure described in example 35.1, 3-chloroaniline was reacted with 4,5-difluoro-2-nitro-benzaldehyde (Daubie, Christophe; Legrand, Jean Jacques; Pemberton, Clive. Eur. Pat. Appl. (1993), EP 538 100 A1) in the presence of Na2SO4, indium and iodine to give the title compound as brown solid. MS: m/e=388.0 [M−H−].
