288-36-8, name is 1H-1,2,3-Triazole, 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. 288-36-8
To a solution of 3-chloro-4-fluoronitrobenzene (1.2 g, 6.836 mmol) and 2H-1,2,3-triazole (0.567 g, 8.203 mmol) in anhydrous DMA (5 mL) was added K2CO3 (1.89 g, 13.7 mmol). The reaction mixture was stirred at 55 C. overnight. The reaction was concentrated to give a crude oil. The crude product was purified by flash column chromatography over silica gel (petroleum ether/ethyl acetate from 100/0 to 20/80) to give compound 4d (1 g, 65.1%) as a yellow solid. 1H NMR (400 MHz, CDCl3) delta ppm 7.88-8.02 (m, 3H), 8.28 (dd, J=8.93, 2.54 Hz, 1H), 8.49 (d, J=2.21 Hz, 1H).
Statistics shows that 288-36-8 is playing an increasingly important role. we look forward to future research findings about 1H-1,2,3-Triazole.
