Adding a certain compound to certain chemical reactions, such as: 31108-57-3, name is 1H-Pyrazole-4-carbonitrile, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 31108-57-3, Computed Properties of C4H3N3
Preparation 8 ethyl 2-(4-cyano-lH-pyrazol-l-yl)acetate [0151] Combined lH-pyrazole-4-carbonitrile (0.432 g, 4.64 mmol) in acetone (9.28 mL), potassium carbonate (1.924 g, 13.92 mmol) and ethyl 2-bromoacetate (1.027 mL, 9.28 mmol). The reaction mixture was stirred at room temperature overnight, then concentrated in vacuo, diluted with EtOAc (10 mL), washed with water (10 mL), dried (MgS04) and concentrated in vacuo to give a residue. The residue was purified using flash column chromatography on silica gel (EtOAc in heptane, 10-50% gradient) to give a white solid. The solid was suspended in heptane and then filtered and dried to give the title compound (0.4314 g, 51.9 % yield) as a white solid. XH NMR (400 MHz, DMSO-i) delta ppm 1.21 (t, J=7.20 Hz, 3 H) 4.17 (q, J=7.07 Hz, 2 H) 5.19 (s, 2 H) 8.11 (s, 1 H) 8.57 (s, 1 H). MS m/z [M+H]+ 180.
