Adding a certain compound to certain chemical reactions, such as: 29509-06-6, name is 4-Methyl-3-oxopentanenitrile, belongs to nitriles-buliding-blocks 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 29509-06-6, Computed Properties of C6H9NO
Sodium hydride (60%, 11.52 g, 287 mmol) in a round bottomflask was cooled using an ice-water bath and kept under nitrogenatmosphere on a Schlenk line. Anhydrous acetonitrile (15.0 mL,287 mmol) and 9.0 mL of anhydrous DMSO were added to the flaskand the mixture was stirred for 30 min. Methyl isobutyrate(33.0 mL, 29.3 g, 287 mmol) was added to the reaction mixture.After stirring for approximately 2 h, the reaction mixture turnedinto a thick white solid. The excess NaH in the reaction mixturewas quenched by slow addition of deionized water. NH4Cl(30.7 g) was added to fully protonate the product, which immediatelygave a milky white suspension. The product was thenextracted three times (150 mL each) with ethyl acetate. All organiclayers were combined and washed with NaCl brine. The organiclayer was dried over anhydrous MgSO4 and filtered. To this solutionwas added 16.0 ml (13.1 g, 110 mmol) of DMF-DMA and thereaction was stirred for 18 h, after which the solvent was removedunder reduced pressure and the product (2-isobutyryl-3-dimethylaminoacrylonitrile) purified by column chromatographyusing CHCl3 as the mobile phase. The solvent was removed andthe product dissolved in 50 mL of methanol. Hydrazine hydrate(8.0 mL, 78 mmol) was added and the reaction stirred overnight.Solvent was removed under reduced pressure and the productpurified by column chromatography using 50:50 ethyl acetate/hexanes to give 2e as a light yellow powder (5.86 g, 43.4 mmol,15% yield based on acetonitrile).
