실험 절차
The 4-chloro-1-(3-pyridyloxy)butane (2.00 g, 10.8 mmol) was dissolved in methanol (25 mL) and added to concentrated ammonium hydroxide solution (29.7%, 14.8 M, 50 mL) in a heavy-walled glass pressure-tube apparatus. The tube was sealed and the mixture was stirred and heated at 100° C. (oil bath temperature) for 6 h. After cooling, the mixture was concentrated by rotary evaporation. Saturated NaCl solution (10 mL) was added to the residue, and the solution (pH 6) was extracted with ether (3×25 mL) to remove impurities. The aqueous layer was basified to pH 10 with 10% NaOH solution, and the mixture was extracted with chloroform (4×25 mL). The combined chloroform extracts were dried (Na2SO4), filtered, and concentrated by rotary evaporation to a residue that was dried briefly under high vacuum to give 1.25 g (74.2%) of an oil.
