Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 288-13-1, name is 1H-Pyrazole, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 288-13-1<\/a><\/p>\n

To a solution of copper(I) oxide (0.906 g, 6.33 mmol), salicylaldoximine (3.47 g, 25.3 mmol), 1H-pyrazole (12.93 g, 190 mmol), and cesium carbonate (66.0 g, 203 mmol) in acetonitrile (50.6 ml) under a nitrogen stream was added 3-bromopyridine (20 g, 127 mmol). The reaction mixture was heated at reflux for 24H. The reaction mixture was allowed to cool to ambient temperature, and then diluted with EtOAc, filtered through celite, and washed with H2O and saturated brine solution. The organics were separated, dried with MgSO4, filtered and concentrated in vacuo. The residue was purified by column chromatography eluting with 0-50% acetone in hexanes to afford 3-(1H-pyrazol-1-yl)pyridine as a yellow oil (17 g, 93%): 1H NMR (400 MHz, acetone-d6) delta 9.14 (d, J=2.2 Hz, 1H), 8.54 (d, J=3.8 Hz, 1H), 8.45 (dd, J=2.5, 0.5 Hz, 1H), 8.24 (ddd, J=8.3, 2.7, 1.5 Hz, 1H), 7.79 (d, J=1.5 Hz, 1H), 7.53 (ddd, J=8.3, 4.7, 0.7 Hz, 1H), 6.59 (dd, J=2.5, 1.8 Hz, 1H); EIMS m\/z 145.<\/p>\n

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 288-13-1.<\/p>\n
