Synthetic Route of 138624-97-2, New Advances in Chemical Research in 2021.In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 138624-97-2, name is 1-Benzyl-1H-1,2,4-triazole-3-carboxylic acid, molecular formula is C10H9N3O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
A mixture of (3R)-3-amino- 1, 8-dimethyl-4,5-dihydro-3H-pyrido [3,4-b] azepine-2,7-dione (15 mg, 0.07 mmol), 1-hydroxybenzotriazole (11 mg, 0.08 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimidehydrochloride (16 mg, 0.08 mmol) and 1 -benzyl1,2,4-triazole-3-carboxylic acid (17 mg, 0.08 mmol) in N,N-dimethylformamide (3 mL) was stirred at 25 C for 2 h. The mixture was concentrated under reduced pressure and the residue was purified by RP-HPLC (acetonitrile 20-50% / 0.05% ammonium hydroxide in water)afford arbitrarily assigned (R)- 1 -benzyl-N-( 1, 8-dimethyl-2,7-dioxo-2,3 ,4,5 ,7 ,8-hexahydro-1 H-pyrido [3,4-b] azepin-3-yl)- 1 H-i ,2,4-triazole-3-carboxamide (21.2 mg, 76%) as a white solid. ?H NMR (400 MHz, CD3OD) 8.56 (s, 1H), 7.87 (s, 1H), 7.37 – 7.33 (m, 5H), 6.49 (s, 1H), 5.47 (s, 2H), 4.71 – 4.65 (m, 1H), 3.59 (s, 3H), 3.33 (s, 3H), 2.74 – 2.69 (m, 2H), 2.45 – 2.38 (m, 1H), 2.13 – 2.08 (m, 1H). LCMS RT = 0.702mi m/z = 407.1 [M + H]. LCMS (5 to 95% acetonitrile in water + 0.1% formic acid over1.5 mins) retention time 0.702 mi ESI+ found [M+H] = 407.1.
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 1-Benzyl-1H-1,2,4-triazole-3-carboxylic acid, hurry up and to see.
