In this short note communication, we report the synthesis of a novel amide 4’-methyl-2’-(quinolin-8-ylcarbamoyl)-biphenyl-4-carboxylic acid ethyl ester by the Ru-catalyzed C(sp2)-H bond arylation reaction. The catalytic C-H bond functionalization reaction was employed, amongst other reaction reagents and conditions, [RuCl2(p-cymene)]2 as a precatalyst and (p-tol)3P as a ligand. The arylation product was characterized by various spectroscopic methods (1H NMR, 13C NMR, IR, GC-MS, and IR spectroscopy), and its composition was confirmed by elemental analysis.

The title compound, N-benzo[c][1,2,5]thiazol-4-yl-3-trifluoromethylbenzamide (1) was synthesized by reacting 3-trifluoromethylbenzoyl chloride (4) and 4-aminobenzo[c][1,2,5]thiadiazole (5). The compound was characterized by various spectroscopic methods (1H NMR, 13C NMR, IR, GC-MS) and its composition confirmed by elemental analysis. The importance of this compound lies in its possession of an N,N-bidentate directing group. Such a structural motif is potentially suitable for metal-catalyzed C-H bond functionalization reactions.
