As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 100-37-8, name is 2-(Diethylamino)ethanol, molecular formula is C6H15NO, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. 100-37-8
1. Synthesis of diethyl-[2-(2-methyl-[1,10]phenanthrolin-4-yloxy)-ethyl]amine To a suspension of sodium hydride (60% in mineral oil, 5.25 g, 131.1 mmol) in anhydrous THF (90 mL) a solution of N,N-diethyl-2-hydroxyethylamine (15.30 g, 131.1 mmol) in anhydrous THF (60 mL) was slowly added. The mixture was stirred at room temperature for 20 minutes and a solution of 4-chloro-2-methyl-[1,10]phenanthroline(6.00 g, 26.2 mmol) in anhydrous THF (90 mL) was slowly added. The reaction mixture was refluxed for 18 hours and then allowed to cool down to room temperature, quenched with 1 N HCl and evaporated. The residue was redissolved in 1N NaOH (150 mL) and extracted with methylene chloride (3 x 200 mL). The combined organic layers were dried (Na2SO4), filtered and concentrated in vacuo. The residue was washed with hexane and purified by flash chromatography (SiO2, MeOH/DCM, 1:40) to yield the pure product as an orange oil (5.1 g, 63%).
The chemical industry reduces the impact on the environment during synthesis 100-37-8, I believe this compound will play a more active role in future production and life.
