反応手順

In another particular, which includes a quinazoline that is substituted by two different reactive groups at positions 6 and 7 thereof, 3,4-dichloro-6-fluoroaniline is reacted with 4-chloro-7-fluoro-6-nitroquinazoline, so as to produce 4-[(3,4-dichloro-6-fluorophenyl)amino]-7-fluoro-6-nitroquinazoline. The 4-[(3,4-dichloro-6-fluorophenyl)amino]-7-fluoro-6-nitroquinazoline is then reacted with a sodium salt of 3-(4-morpholinyl-1-propanol), so as to produce 4-[(3,4-dichloro-6-fluoro-phenyl)amino]-7-[3-(4-morpholinyl)propoxy]-6-nitroquinazoline, which is reduced, by means of an ethanolic solution of hydrazine hydrate and Raney®Nickel, so as to produce 6-amino-4-[(3,4-dichloro-6-fluorophenyl)amino]-7-[3-(4-morpholinyl)propoxy]quinazoline. The product is then reacted with a carbon-11 labeled acryloyl chloride so as to produce a carbon-11 labeled N-{4-[(3,4-dichloro-6-fluorophenyl)amino]-7-[3-(4-morpholinyl)propoxy]quinazoline-6-yl}acrylamide (carbon-11 labeled morpholino-substituted Compound 3).
