Hydrochloric Acid → (4-Methoxyphenyl)glycolonitrile

Participants

Reaction Steps

To 49 g (1 mole) of sodium cyanide and 136 g (1 mole) anisaldehyde in ethyl alcohol 800 ml), containing triethylamine (5 mol %, 5.1 g) is added HCl gas (1 mol, 36.5 g) over 30 minutes at 5°-10° C. The resulting slurry is stirred at that temperature for 6 hours. In situ sampling of the reaction mixture shows the reaction to be complete. Additional HCl (0.2 moles) is added to quench the reaction. tHE solution is filtered and used in the next step without further purification. Yield, ca. 80%.
