Reaction Steps

Hydrogen chloride gas is bubbled through a suspension of 2 moles (354 g) of homoveratronitrile in 161 mL of pyridine, with stirring and under a nitrogen atmosphere. As soon as the temperature reaches 115° C. and becomes stable, the bubbling is discontinued; the reaction medium is heated to 170° C. for 3 hours. During this period, hydrogen chloride is bubbled through for 5 to 10 minutes at approximately half-hourly intervals. When the reaction has ended, the reaction mixture is poured into a mixture of ice and water (1.2 kg).
