Application of 3616-56-6, The chemical industry reduces the impact on the environment during synthesis 3616-56-6, name is 2,2-Diethoxy-N,N-dimethylethanamine, I believe this compound will play a more active role in future production and life.
(a) 2-(N,N-dimethylaminomethyl)chroman-4-one Dimethylaminoacetaldehyde diethyl acetal (40 g) was treated below -5¡ã C. with conc. hydrochloric acid (196 ml) and then stirred at room temperature for 2 hours. After the solution had been neutralised with sodium bicarbonate, 2 N sodium hydroxide (80 ml) was added followed by 2-hydroxyacetophenone (34 g) in 2 N sodium hydroxide (80 ml) and sufficient dioxane to give a single phase reaction mixture. The solution was heated at 70¡ã-80¡ã C. with stirring for 21/2 hours and left at ambient temperature overnight. Extraction with diethyl ether was followed by extraction of the organic phase with dilute hydrochloric acid. The aqueous acid solution was basified with sodium hydroxide solution and extracted into diethyl ether to give the title compound (3.4 g) as an oil. 1 H nmr (CDCl3) delta: 8.1-6.9 (m, 4H); 4.9-4.4 (m, 1H); 3.0-2.5 (m, 4H); 2.3 (s, 6H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2,2-Diethoxy-N,N-dimethylethanamine, other downstream synthetic routes, hurry up and to see.
