Brief introduction of 3-Aminopropanenitrile

Application of 151-18-8, A common heterocyclic compound, 151-18-8, name is 3-Aminopropanenitrile, molecular formula is C3H6N2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

Example 7; N-Cbz-3-aminopropionitriIe (18).; 3-Aminopropionitrile 17 (0.56 g, 8.0 mmol) was suspended in water (10 mL) and THF (10 mL). The pH was adjusted to 9.0 by addition of NaOH (0.2 g, 5 mmol). Benzyl chloroformate (1.7 g, 10 mmol) was added dropwise over 2 h at 20-25 0C to the resulting clear solution, and the pH EPO was kept constant at 9.0 by addition of aqueous NaOH (4 M, 2.5 mL). The mixture was stirred for 1 h at pH 9.0, extracted with ethyl acetate, and dried with Na2SO4. The solvents were removed by rotary evaporation to give crude 18 (1.6 g, 98%) as an oil. 1H NMR (400 MHz, OMSO-d6) delta.3 (s, 5H), 5.0 (s, 2H), 3.22 ~ 3.27 (m, 2H), 2.6 (t, 2H5 J= 6.4 Hz).

The synthetic route of 151-18-8 has been constantly updated, and we look forward to future research findings.
