実験手順
A Schlenk tube is charged with 5.5 g (52 mmol) of potassium imidazolide in 50 ml of THF. While stirring, 7.7 g (50 mmol) of 2-bromoethyl ethyl ether are added and the suspension is stirred for 4 hours, then warmed gently. After cooling, the reaction mixture is filtered and the solvent is removed. Distillation in a high vacuum gives 7a as a colorless liquid. The purity was checked by GC-MS. Only one fraction was observed here.
