Versuchsvorschrift
To a solution of [(4-dimethylaminophenyl)methyl](4-fluorophenyl)amine (0.52 g) in benzene (5 mL) was added 2,6-diisopropylphenyl isocyanate (0.46 mL) and the mixture was stirred at room temperature for 5 hr. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography. The obtained crystals were subjected to recrystallization from a mixed solvent of diisopropyl ether and hexane to give N′-(2,6-diisopropylphenyl)-N-[(4-dimethylaminophenyl)methyl]-N-(4-fluorophenyl)urea (0.38 g). melting point: 124–125° C.
