Potassium Cyanide → HCID 15572607, compound

Participants

Reaction Steps

150 g of α-(2-methoxy-phenoxy)-phenyl acetaldehyde dissolved in approximately 1800 ml of diglyme was stirred with 176.5 g of sodium metabisulphite in 550 ml of water and 200 ml of ethanol at 50° C. for 16 hours. The whole was cooled to room temperature and addition was made of 44.4 g of potassium cyanide in 200 ml of water. The whole was stirred at 90° C. (external temperature) for 5 hours, concentrated to approximately 800 ml and poured into water: extraction was performed with 4×750 ml of ethyl ether and the whole washed with water, dried over Na2SO4 and evaporated to dryness to obtain 156.5 g of 2-hydroxy-3-phenyl-3-(2-methoxy-phenoxy)-propionitrile as a viscous oil. Yield=94%. Analogously, all the 2-hydrox-propionitrile derivatives useful for the preparation of the 2-hydroxy-propylamines mentioned in Examples 3 and 4 were prepared.
