      abstract     = {Four different no carrier added (n.c.a.)
                      4-[F-18]fluorophenylurea derivatives are synthesized as
                      model compounds via two alternative routes. In both cases
                      carbamate-4-nitrophenylesters are used as intermediates.
                      Either n.c.a. 4-[F-18]fluoroaniline reacts with carbamates
                      of several amines, or the carbamate of n.c.a.
                      4-[F-18]fluoroaniline is formed at first and an amine is
                      added subsequently to yield the urea derivative. The choice
                      of the appropriate way of reaction depends on the
                      possibilities of precursor synthesis. The radiochemical
                      yields reach up to $80\%$ after 50min of synthesis time
                      while no radiochemical by-products can be determined. These
                      high yields were possible due to an optimized preparation of
                      n.c.a. 4-[F-18]fluoroaniline with a radiochemical yield of
                      up to $90\%.$ From the various ways of its radiosynthesis,
                      the substitution with n.c.a. [F-18]fluoride on
                      dinitrobenzene is chosen, using phosphorous acid and
                      palladium black for reduction of the second nitro group. (c)
