Sodium Iodide → 1-[2-(1-Adamantyl)ethyl]-1-[2-[N-(2-methoxyethyl)-N-methylamino]ethyl]-3-[3-(4-pyridyl)propyl]urea

온도

80 °C

To N,N-dimethylformamide (20 ml) were added 1-[2-(1-adamantyl)ethyl]-1-(2-methylaminoethyl)-3-[3-(4-pyridyl)propyl]urea (1.50 g, 3.76 mmol), which is a free base of Compound No. 3-1, potassium carbonate (1.56 g, 11.3 mmol) and sodium iodide (1.69 g, 11.3 mmol) at room temperature, then 2-chloroethyl methyl ether (412 μl, 4.51 mmol) was added to the mixture, and the whole was heated at 80° C. and stirred overnight, then diethyl ether (50 ml) and water (100 ml) were added to the reaction mixture. After extraction, the obtained organic layer was washed with water (100 ml) and a saturated aqueous sodium chloride solution (50 ml) successively, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give the target compound (552 mg, 32.1%) as a pale yellow oily matter.
