An alternative strategy for the synthesis of 1-aryl- and 1-alkyl-2-methylsulfanyl-4-(4-fluorophenyl)-5-(pyridin-4-yl)imidazoles as potential p38α mitogen-activated protein kinase inhibitors is reported. The regioselective N-substitution of the imidazole ring was achieved by treatment of α-aminoketones with different aryl or alkyl isothiocyanates. In contrast to previously published synthesis ro...

The synthesis and pharmacological characterization of a series of N-substituted 3-(4-fluorophenyl)tropane derivatives is reported. The compounds displayed binding characteristics that paralleled those of cocaine, and several had substantially higher affinity at cocaine recognition sites. Conjugate addition of 4-fluorophenyl magnesium bromide to anhydroecgonine methyl ester gave 2 beta-(carbomet...

The title compound, C(19)H(12)F(3)NO(4), was synthesized by the reaction of 5-(4-fluoro-phen-yl)-2-furan-methanol and 2,6-difluoro-benzoyl-isocyanate. The seven atoms of the fluorophenyl group are disordered over two positions with site occupancy factors ca 0.6 and 0.4. The dihedral angle between the furan and fluorophenyl rings is 1.58°. In the crystal structure, the mol-ecules are linked via ...
