Reaction Steps

74.0 g (0.48 mol) of diethyl sulphate were added dropwise to a suspension of β-ionol alcoholate [obtained from 65.8 g (0.34 mol) of β-ionol and 18.4 g (ca 0.44 mol) of 55%-60% sodium hydride in 600 ml of benzene] in such a manner that the temperature did not exceed 50° C. Subsequently, the mixture was stirred at reflux for 3 hours, cooled and worked-up as described in Example 1. Crude distillation of the crude product (72.0 g) gave 50.2 g of crude product which were subsequently purified by distillation over a 20 cm Widmer column. There were obtained 47.0 g (66.1%) of pure and olfactorily good β-ionyl ethyl ether 2 of boiling point 120°-122° C./10 mmHg.
