Thionyl Chloride → HCID 19976091, compound

Participants

Reaction Steps

Thionyl chloride (11.9 ml, 163 mmol) was added under a nitrogen atmosphere to a suspension of 2-methoxy-5-phenoxybenzaldehyde oxime (3.96 g, 16.3 mmol) in 75 ml of benzene. There was a slight exotherm and the mixture turned yellow. The reaction was heated to reflux temperature over 1 hour and at reflux temperature for an additional hour. The solvent and excess thionyl chloride were removed under reduced pressure to give 2-methoxy-5-phenoxybenzonitrile as a light tan crystalline solid (3.66 g, 100% ), mp 88°-89° C.
