Reaction Steps

8.5 g (0.1 mol) of 2-methyloxazoline and 14.9 g (0.1 mol) of 3-methyl-2-butenyl bromide were stirred in 50 ml of acetonitrile at 20° to 25° C. for 2 hours and, after adding 20 ml of a 5 N sodium methylate solution, the mixture was stirred at room temperature for a further 3 hours. The solution was filtered and, after stripping off the solvent, the residue was distilled. 15.6 g (84 mmols, 84%) of 2-methoxy-2-methyl-3-(3-methyl-2-butenyl)-oxazolidine of boiling point 96°-99° C./20 mm Hg were obtained.
