Reaction Conditions

Reaction Steps

8.5 g (0.1 mol) of 2-methyloxazoline and 14.9 g (0.1 mol) of prenyl bromide were stirred in 50 ml of n-hexane at 40° C. for 1 hour, whereupon a suspension formed, which, after adding 0.11 mol of a sodium ethylate solution in ethanol, was again stirred at 40° C. for 1 hour. The solution was filtered, the filtrate was concentrated on a rotary evaporator and the residue was distilled using an oil pump. 12.3 g (0.062 mol, 62%) of 2-ethoxy-2-methyl-3-(3-methyl-2-butenyl)-oxazolidine were isolated at a boiling point 67° C./0.1 mm Hg.
