Adding a certain compound to certain chemical reactions, such as: 2032-34-0, name is 3,3-Diethoxypropanenitrile, 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 2032-34-0, Quality Control of 3,3-Diethoxypropanenitrile
Step 1. l-cyclopropyl-lH-pyrazol-5-amine [0634] A 100-mL round-bottom flask was charged with 3,3-diethoxypropanenitrile (0.600 g, 4.19 mmol), cyclopropylhydrazine di-hydrochloride (0.610 g, 4.21 mmol) and ethanol (20 mL), and the resulting solution stirred for 18 h at 80 C. The reaction mixture was cooled to room temperature and concentrated under vacuum. The residue was purified via column chromatography on silica gel (eluting with 10: 1, dichloromethane/methanol) to afford l-cyclopropyl-lH-pyrazol-5-amine (0.206 g, 36% ) as light yellow oil. MS (ESI, pos. ion) m/z 124[M+H]+.
