反応手順
In a further process disclosed in EP-A 1 116 719, 5-nitro-2(3H)-benzofuranone is reacted in the presence of pentanoic acid and pentanoic anhydride to give 3-(1-hydroxypentylidene)-5-nitro-2(3H)-benzofuranone which reacts under acidic conditions to give 2-(n-butyl)-5-nitrobenzofuran. The disadvantage of this process is that 5-nitro-2(3H)-benzofuranone is used as precursor, which makes industrial application uneconomic.
