Continuously updated synthesis method about 2-Bromo-1,1-dimethoxyethane

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-Bromo-1,1-dimethoxyethane, other downstream synthetic routes, hurry up and to see.

7252-83-7, A common compound: 7252-83-7, name is 2-Bromo-1,1-dimethoxyethane, belongs to ethers-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.

To a mixture of 4-hydroxybenzothioamide (30.64 g, 0.20 mol) and 2-bromo-1,1-dimethoxyethane (31.00 g, 0.20 mol) in EtOH (600 mL) was added 4-methylbenzenesulfonic acid (34.44 g, 0.20 mol) with stirring at rt. The reaction mixture was heated at 90 C. for 24 h, then cooled to rt and concentrated in vacuo. The mixture was diluted with H2O (200 mL), adjusted to pH 10 with saturated NaHCO3 aqueous solution and extracted with DCM (200 mL*3). The combined organic phases were concentrated in vacuo to give the title compound as s yellow solid (21.3 g, 60%).

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-Bromo-1,1-dimethoxyethane, other downstream synthetic routes, hurry up and to see.
