Discovery of 33279-01-5

The chemical industry reduces the impact on the environment during synthesis 3-Oxopentanenitrile. I believe this compound will play a more active role in future production and life.

Application of 33279-01-5, 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. 33279-01-5, name is 3-Oxopentanenitrile, This compound has unique chemical properties. The synthetic route is as follows.

Step 2: Preparation of 3-ethyl-l-(3-methylpyridm-2-ylHH-pyrazol-5-amine; EPO 3-Oxo-pentanenitrile (4.87 g, 26.10 mmol) and diphenylmethanone (3-methyl pyridin-2-yl)hydrazone (5.00 g, 17.40 mmol) were dissolved in anhydrous EtOH (150 mL). TsOH (3.31 g, 17.4 mmol) and cone. HCl (14.29 mL, 174.0 mmol) were added to the solution. The mixture was heated at reflux overnight. Additional 3-oxo-pentanenitrile (4.87 g, 26.10 mmol) was added. The mixture was refluxed another 24 h. EtOAc was added. The resulting mixture was basified by slow addition of sat. Na2CO3. The organic layer was dried over MgSO4 and then concentrated. Column chromatography purification (25% EtOAc/ hexane) afforded the title compound as a light yellow oil (1.5 g, 42.6%). 1H NMR (400 MHz, DMSO-d6) delta 8.35-8.34 (IH, d, J = 2.8 Hz), 7.86-7.84 (IH, d, J = 9.6 Hz), 7.39-7.36 (IH, t, J =4.5 Hz), 5.46 (IH, S), 2.58-2.52 (2H, q, J = 6.0 Hz), 2.30 (3H, s), 1.26-1.23 (3H, t, J = 4.2 Hz); LC-MS m/z 203.1 (MH+), HPLC RT (min) 1.07 {method (A)}.

The chemical industry reduces the impact on the environment during synthesis 3-Oxopentanenitrile. I believe this compound will play a more active role in future production and life.
