Reaction Steps

A mixture of 1.9 g of p-(4-pentenyl)benzonitrile and a 10% solution of potassium hydroxide in diethylene glycol was boiled at 180° C. for 2 hours. The reaction mixture was then cooled to room temperature, adjusted to pH 3 with 23% hydrochloric acid, diluted with water and extracted four times with methylene chloride. The organic phases were washed twice with water, dried over magnesium sulphate, filtered and concentrated, whereby 2.12 g of p-(4-pentenyl)benzoic acid were isolated as brown crystals.
