Friedel-Crafts acylation for the synthesis of aryl- and heteroaryl-(3-ethyl-4-nitrophenyl)-methanones

Friedel-Crafts acylation for the synthesis of aryl- and heteroaryl-(3-ethyl-4-nitrophenyl)-methanones

The present invention concerns a synthesis process comprising the following steps (i) reacting 3-ethyl-4-nitrobenzoic acid with thionyl chloride to produce a 3-ethyl-4-nitrobenzoic acid chloride or a 3-ethyl-4-nitrobenzoic acid anhydride from 3-ethyl-4-nitrobenzoic acid by means of water cleavage an...

description The present invention concerns a synthesis process comprising the following steps (i) reacting 3-ethyl-4-nitrobenzoic acid with thionyl chloride to produce a 3-ethyl-4-nitrobenzoic acid chloride or a 3-ethyl-4-nitrobenzoic acid anhydride from 3-ethyl-4-nitrobenzoic acid by means of water cleavage and (ii) Friedel-Crafts acylation by reacting the 3-ethyl-4-nitrobenzoic acid chloride or the 3-ethyl-4-nitrobenzoic acid anhydride with an optionally substituted aryl-H to form an optionally substituted (3-ethyl-4-nitrophenyl)-aryl-methanone. In addition the present invention concerns compounds containing (3-ethyl-4-nitrophenyl)-aryl-methanone, characterized in that the optionally substituted aryl is an optionally substituted condensed aromate.
