27996-86-7, name is 4-[1,2,4]Triazol-1-yl-benzaldehyde, belongs to Triazoles compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Product Details of 27996-86-7
A mixture of malonitrile (128 mg, 1.94 mmol) and 4-(1H-1,2,4-triazol-1- yl)benzaldehyde (336 mg, 1.94 mmol) in 8 mL of anhydrous ethanol was charged with N- methylmorpholine (0.21 mL, 1.94 mmol) for 10 min. To the mixture was added 1,3-dimethyl- 1H-pyrazol-5(4H)-one (214 mg, 1.94 mmol) in one portion at room temperature. The reaction mixture was stirred at room temperature for 48 hrs. The reaction mixture was concentrated on rotavapor to dryness and the resulting crude product was purified by Teledyne-Isco flash system by using CH2Cl2/MeOH, 5 to 10% of methanol in dichloromethane to provide compound 33 as a viscous solid (500 mg, 77%).1H NMR (400 MHz, DMSO-d6) delta (ppm): 8.68 (s, 1H), 7.63 (s, 1H), 7.22 (d, J = 8.0 Hz, 2H), 6.78 (d, J = 8.4 Hz, 2H), 6.54 (s, 1H), 4.10 (s, 1H), 3.02 (s, 3H), 2.74 (s, 2H), 1.11 (s, 3H). MS (ESI): Calcd for C17H15N7O: 333, found: 334 (M+H)+.
The synthetic route of 27996-86-7 has been constantly updated, and we look forward to future research findings.
