Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 4928-87-4, name is 1,2,4-Triazole-3-carboxylic acid, A new synthetic method of this compound is introduced below., SDS of cas: 4928-87-4
To a reaction of 1/7-1, 2, 4-triazole-3 -carboxylic acid (100 mg, 0.87 mmol) and 4- Methoxy-3- (trifluoromethyl)benzylamine (200 mg, 0.97 mmol) in dry DMF (10 mL) was added 1- hydroxybenzotriazole monohydrate (146 mg, 0.97 mmol) and EDC (N-(3- Dimethylaminopropyl)-N’-ethylcarbodiimide) (186 mg, 0.97 mmol) followed by N- methylmorpholine (0.38 mL, 3.48 mmol via syringe). The mixture was stirred at room temperature under nitrogen and the solids were gradually dissolved. The contents were stirred at room temperature for 24.0 h, and then slowly diluted into iced water and extracted with DCM (2 x 50 mL). The DCM phase was washed with ice cold water (2 x 100 mL). The DCM phase was dried over anhydrous Na2S04, filtered and concentrated under reduced pressure and chromatographed on silica gel using EtOAc as eluents to get the desired amide 10 (62.8 mg, 24 % yield) as a white solid compound. -NMR (400 MHz, DMSO-de): <514.66 (br s, 1H), 9.23 (br s, 1H), 8.49 (br s, 1H), 7.60-7.58 (m, 2H), 7.22 (d, J= 8.4 Hz, 1H), 4.43 (d, J= 6 Hz, 2H), 3.86 (s, 3H); 19F -NMR (376 MHz, DMSO-de): <5 -60.82 ppm. MH+ = 301.4 m/z.
The synthetic route of 4928-87-4 has been constantly updated, and we look forward to future research findings.
