3-Bromoaniline → N-(3-Bromophenyl)-6-nitroquinazolin-4-amine

참여 물질

반응 단계

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 triethylamine solution as the reaction catalyst, as is described hereinabove. The stanylated quinoline is then reacted with iodine-123 or iodine-131, in the presence of an oxidizing agent, to produce iodine-123 labeled or iodine-131 labeled 4-[(3-iodophenyl)amino]-6-aminoquinazolie, which is further reacted with 4-bromocrotonyl chloride and dimethylaniline, as described, to yield the final iodine-123 or iodine-131 labeled product.
