Reaction #433610

Reaction equation

3-Bromoaniline

4-chloro-7-fluoro-6-nitroquinazoline

→

4-[(3-bromophenyl)amino]-7-fluoro-6-nitroquinazoline

Conditions

Procedure

3-Bromoaniline is coupled with 4-chloro-7-fluoro-6-nitroquinazoline, to produce 4-[(3-bromophenyl)amino]-7-fluoro-6-nitroquinazoline, which is reacted thereafter with the sodium salt of 3-(4-morpholinyl)-1-propanol, as described hereinabove, to produce 4-[(3-bromophenyl)amino]-7-[3-(4-morpholinyl)propoxy]-6-nitroquinazoline. The morpholino-substituted 6-nitroquinazoline is then reduced to the corresponding 6-aminoquinazoline, which is further reacted with bistributyltin, iodine-123, iodine-124 or iodine-131 and acryloyl chloride, as described hereinabove, to yield the final iodine-123 labeled, iodine-124 labeled or iodine-131 labeled product.
