실험 절차

To a solution of 2-chloro-4-(trifluoromethyl)aniline (500 mg, 2.56 mmol) in tetrahydrofuran (THF) (8 mL) was added 1H-1,2,3-benzotriazole-1-carbaldehyde (489 mg, 3.32 mmol, Sigma-Aldrich). The reaction mixture was heated to 70° C. and stirred for 18 hours. To the reaction mixture was added 1H-1,2,3-benzotriazole-1-carbaldehyde (1.16 mmol, 245 mg) and the reaction mixture heated to 70° C. for a further 5 hours. The reaction mixture was concentrated under vacuum and the residue partitioned between DCM (20 mL) and 2N HCl (10 mL). The organic layer was collected via a hydrophobic frit and the solvent removed under vacuum.
