106984-09-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 106984-09-2, name is tert-Butyl (2-(2-(2-(2-hydroxyethoxy)ethoxy)ethoxy)ethyl)carbamate belongs to amides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
To a solution of tert-butyl (2-(2-(2-(2-hydroxyethoxy)ethoxy)ethoxy)ethyl)carbamate (10.0 g, 34.1 mmol, Step 1 of Intermediate EN) in anhydrous THF (250 mL) was added sodium hydride (1.63 g, 40.94 mmol, 60% dispersion in mineral oil) in one portion under nitrogen atmosphere. The reaction mixture was stirred at rt for 0.5 h and thereafter it was cooled to 0 C. An 80% solution of 3-bromoprop-1-yne in toluene (5.7 mL, 51.2 mmol) was added dropwise to the reaction mixture at 0 C. over a period of 10 min. The resulting reaction mixture was stirred at 0 C. for 1 h and thereafter it was allowed to warm to rt. The resulting reaction mixture was stirred overnight at rt. Then the reaction mixture was quenched with a small aliquot of methanol (1.6 mL) and concentrated on a rotary evaporator. The obtained crude material was suspended in DCM (100 mL) and was washed with water (2¡Á30 mL) and brine (50 mL). The resulting organic layer was dried over anhydrous sodium sulphate, filtered and concentrated on a rotary evaporator. The obtained crude product was purified by silica gel chromatography (gradient Ethyl acetate/Hexanes) to give the title compound (6.25 g, 55%) as a light yellow viscous liquid.
The synthetic route of 106984-09-2 has been constantly updated, and we look forward to future research findings.
