HCID 20351118HCID 20351118, compound

Procedure

By reacting 5-trifluoromethylisatin with phosphorus pentachloride, there is obtained 5-trifluoromethylisatin chloride which, on reation with 3(2H)-thianaphthenone, yields 5'-trifluoromethyl-2'-indole-2-thianap indigo, which also is useful as a dyestuff.
