Reaktionsschritte
14.9 g (0.1 mol) of prenyl bromide and 8.5 g (0.1 mol) of 2-methyl-oxazoline were stirred in 50 ml of methylene chloride at 25° C. for 2 hours and the mixture was treated with 0.11 mol of a sodium butylate solution in n-butanol at 40° C. for 1 hour and worked up in the customary manner. 13.4 g (59 mmols, 59%) of 2-butoxy-2-methyl-3-(3-methyl-2-butenyl)-oxazolidine were obtained by distillation at a boiling point 78°-80° C./0.3 mm Hg.
