실험 절차
To a solution of N,N-dimethylethanolamine (0.36 mL) in THF (15 mL) was added sodium hydride (145 mg). After stirring at room temperature for 10 minutes, 5-bromo-2-chloropyrimidine (500 mg) was added and the mixture heated at reflux for 16 h. After cooling to room temperature, the mixture was extracted into 2 M aqueous HCl solution (30 mL) and washed with ethyl acetate (30 mL). The aqueous layer was made basic with sodium carbonate and the product extracted into ethylacetate (3×30 mL). The organic layers were dried (MgSO4) and reduced in vacuo to give [2-(5-bromo-pyridin-2-yloxy)-ethyl]-dimethylamine as a white solid.
