実験手順: To the ice-cold solution of ammonium hydroxide (25 mL, 159 mmole) of 25% (w/w) was added glycidyldiethylamine dropwise (3.2 g, 24.8 mmol) over 10 minutes. The reaction mixture was stirred at 0–5° C. for 1 hour and then room temperature for 14 hours. The resulting reaction mixture was evaporated and distilled (84–90° C. at 500–600 mT) to yield 1-amino-3-diethylamino-propan-2-ol (3.3 g, 92%). MS m/z 147 ([M+1]+.). room temperature for 14 hours The resulting reaction mixture was evaporated distilled (84–90° C. at 500–600 mT)

実験手順: A solution of sodium hydroxide (47.9 g, 1.2 mole) in 78 mL water was added 1-chloro-3-diethylamino-propan-2-ol. The resultant was stirred at 20–25° C. for 1 hour, diluted with 178 mL of water and extracted with ether twice. The combined ether solution was dried with solid potassium hydroxide and evaporated to give 135 g of crude product which was purified by fraction distillation to give pure glycidyldiethylamine (98 g, 76%) as an oil. extracted with ether twice The combined ether solution was dried with solid potassium hydroxide evaporated to give 135 g of crude product which was purified by fraction distillation

実験手順: 0.2 Mole of the 1-diethylamino-2,3-epoxypropane thus prepared is added, drop by drop, to 12.8 g of the cyanamide monosodium derivative dissolved in 200 cc of anhydrous methanol with vigorous stirring. After 15 hours of stirring at ambient temperature, the methanol is evaporated and the residue picked up with 300 cc of ether. The precipitate is eliminated by filtering. The ether phase is washed twice with 2 cc of water then dried on Na2SO4 after decanting. The ether is evaporated under low pressure. The resulting oily phase crystallizes after washing with boiling heptane. 2-Amino-5-diethylaminomethyl-2-oxazoline is thus obtained with a yield of 68%. It is purified by recrystallization in heptane. is added the methanol is evaporated by filtering The ether phase is washed twice with 2 cc of water then dried on Na2SO4 after decanting The ether is evaporated under low pressure The resulting oily phase crystallizes after washing with boiling heptane
