HCID 2735739Benzonitrile, 3-chloro-4-hydroxy-

Procedure

The title compound was prepared from 3-chloro-4-hydroxybenzaldehyde and hydroxyl ammonium chloride, using the same method as that described for preparation 70. The title compound was purified by column chromatography on silica gel, eluting with pentane:ethyl acetate, 100:0 to 90:10, to afford the title compound as a white solid in 76% yield.
