2-Chloro-5-nitrobenzotrifluoride → HCID 54090398, compound

Participants

Reaction Steps

A mixture of 1-octadecyllepidinium p-toluenesulfonate (24.6 g.), 2-chloro-5-nitrobenzotrifluoride (10 g.) and acetonitrile (700 ml.) was treated with diisopropylethylamine (20.7 g.) and refluxed for 6 hours with stirring. After filtering and evaporating, 1,4-dihydro-4-(4-nitro-2-trifluoromethylbenzylidene)-1-octadecylquinoline was formed. This colored dye was changed to the colorless compound having the formula: ##STR5## by reacting with a molar equivalent of p-toluenesulfonic acid in methanol.
