Versuchsvorschrift

56.5 Grams of p-(1-cyclohexenyl)-anisol and 125 g of pyridine-hydrochloride are thoroughly mixed and heated for 3 hours in an atmosphere of nitrogen to 180° C. The reaction mixture is cooled to room temperature, treated with water and extracted with 3 × 400 ml of benzene. The benzene extracts are washes with 3 × 300 ml of water, dried over sodium sulphate and evaporated in vacuo. The solid residue yields the crude p-(1-cyclohexenyl)-phenol (m.p. 115-119° C), which can be purified by recrystallisation from benzene and then melts at 120°-122° C.
