Abstract
NEW MATERIAL:A compound expressed by formula I (X is halogen; n is 2 or 3; R<1> is H or acetyl; R<2> is H or amino; provided that at least one of (X)n is bromine). EXAMPLE:1-Acetyl-5-bromo-7-iodoindoline. USE:An intermediate for producing medicine, agricultural chemical, etc. PREPARATION:A compound expressed by formula II (X<1> is halogen substituting at 5- or 6-position) is reacted with thallium tristrifluoroacetic acid to afford a compound expressed by formula III, which is then reacted with a halide such as KI, copper (II) bromide or copper (II) chloride to provide the compound expressed by formula I (R is H).
