Versuchsvorschrift
In one particular, 3,4-dichloro-6-fluoroaniline is reacted with 4-chloro-6-nitroquinazoline, so as to produce 4-[(3,4-dichloro-6-fluorophenyl)amino]-6-nitroquinazoline, which is reduced, by means of an ethanolic solution of hydrazine hydrate and Raney®Nickel, so as to produce 4-[(3,4-dichloro-6-fluorophenyl)amino]-6-aminoquinazoline. Then, the 4-[(3,4-dichloro-6-fluorophenyl)amino]-6-aminoquinazoline is reacted with 4-bromocrotonyl chloride, so as to produce 4-bromo-N-{4-[(3,4-dichloro-6-fluorophenyl)amino]quinazoline-6-yl}-2-butenamide, which is then reacted with methylamine, so as to produce N-{4-[(3,4-dichloro-6-fluorophenyl)amino]quinazoline-6-yl}-4-(methylamino)-2-butenamide. The obtained methylamino derivative of the butenamide is reacted with a carbon-11 labeled methyliodide, so as to produce a carbon-11 labeled N-{4-[(3,4-dichloro-6-fluorophenyl)amino]quinazoline-6-yl}-4-(dimethylamino)-2-butenamide (carbon-11 labeled Compound 4).
