Versuchsvorschrift

3-Bromoaniline is coupled with 4-chloro-6-nitroquinazoline, to produce 4-[(3-bromophenyl)amino]-6-nitroquinazoline, which is reduced thereafter to the corresponding 6-aminoquinazoline. The 4-[(3-bromophenyl)amino]-6-aminoquinazoline is then reacted with bistributyltin, using tetrakis(triphenylphosphine)palladium in THF solution as the reaction catalyst, as is described hereinbelow (see, iodine-124 labeled Compound 5). The stanylated quinazoline is then reacted with bromine-76 or bromine-77, in the presence of an oxidizing agent, to produce bromine-76 labeled or bromine-77 labeled 4-[(3-bromophenyl)amino]-6-aminoquinazoline, which is farther reacted with acryloyl chloride as described, to yield the final bromine-76 labeled or bromine-77 labeled product.
