N-(4-Bromobenzyl)-2-(5,6-dimethyl-1H-benzo[d]imidazol-2-yl)benzeneamine was obtained by condensation of N-(4-bromobenzyl)-3,1-benzoxazine-2,4-dione (N-(4-bromobenzyl)isatoic anhydride) with 4,5-dimethyl-1,2-phenylenediamine in refluxing acetic acid....

Cyclo-condensation of N-methyl-2-bromoaniline with chlorocarbonylsulfenyl chloride (CCSC) promoted by PhNMe2 and AlCl3, afforded N-methyl-2-bromo-2(3H)-benzothiazol-2-one in good yield. Miyaura–Ishiyama cross-coupling of this brominated 2(3H)-benzoth...

An improved procedure for isolation of 5-amino-3-methyl-1,2,4-thiadiazole in pure form on a multi-gram scale without chromatography is reported. Its 1H and 13C-NMR and IR data are presented and previously published erroneous data corrected. The molec...

The two precursors 3-chloro-2-methylphenylthiourea 2 and 4-fluorophenacyl bromide 4 are reacted under Hantzsch thiazole synthesis condition to yield the new compound N-(3-chloro-2-methylphenyl)-4-(4-fluorophenyl)-1,3-thiazol-2-amine 5. The IR, 1H-NMR...

The synthesis of 3-[2-(oxiran-2-yl)ethyl]-1-{4-[(2-oxiran-2-yl)ethoxy]benzyl}imidazolium bis(trifluoromethane)sulfonimide was achieved in seven steps with an overall yield of 63%. This ionic liquid monomer is based on an imidazolium core containing a...

In this study, all four stereoisomers of tryptoline or tetrahydro-β-carboline were synthesized in high yields by the catalyst-free amidation of methyl ester using methylamine under mild conditions. All isomers of the obtained amide and the precursor...
