YieldReaction ConditionsOperation in experiment
19% With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; N-ethyl-N,N-diisopropylamine; In N,N-dimethyl-formamide; at 20℃; for 10h; A solution of [1 ,2,4]triazolo[1,5-a]pyridine-6-carboxylic acid (1 10 mg, 0.67 mmol, 1 .00 equiv), <strong>[94341-56-7]4-benzenesulfonyl-benzylamine</strong> (247 mg, 1 .00 mmol, 1 .50 equiv), EDCI (1 53 mg, 0.80 mmol, 1 .20 equiv), HOBt ( 1 08 mg, 0.80 mmol, 1 .20 equiv), and diisopropylethylamine (258 mg, 3.00 equiv) in DMF (10 mL) was stirred for 10 h at rt. After the reaction completed, the reaction mixture was concentrated under vacuum and the residue was purified on a silica gel column eluted with DCM/MeOH (20: 1 ) to give 50 mg (19%) of the title compound as a white solid. LC/MS (Method D, ESI): RT= 1 .52 min, m/z = 393.0 [M+H]+. 1H NMR (300 MHz, DMSO-d6) delta 9.46 (s, 1 H), 9.40 (m, 1H), 8.62 (s, I H), 8.07 (d, J = 1 .8 Hz, 1 H), 7.90-8.05 (m, 5H), 7.57-7.68 (m, 5H), 4.57 (d, J = 5.7 Hz, 2H).
