Adding a certain compound to certain chemical reactions, such as: 1462-37-9, name is ((2-Bromoethoxy)methyl)benzene, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 1462-37-9, Quality Control of ((2-Bromoethoxy)methyl)benzene
To a suspension of NaH (688 mg, 27.8 mmol) in THF (80 mL) was added diethyl malonate (7.45 g, 46.5 mmol) dropwise. Then ((2-bromoethoxy)methyl)benzene (5 g, 23.2 mmol) was added. The reaction was heated to 90 ¡ãC for 5 hours. After cooling to room temperature, the mixture was diluted with EtOAc (50 mL), washed with water (50 mL x 2), dried over anhydrous Na2S04 and concentrated under vacuum. The crude residue was purified by silica gel chromatography eluting with a gradient of 10percent – 30percent EtOAc/hexanes to afford diethyl 2-(2-(benzyloxy)ethyl)malonate (6.6 g, 22.5 mmol, 81percent yield) as a colorless oil.
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-Bromoethoxy)methyl)benzene, other downstream synthetic routes, hurry up and to see.
