2675-89-0, A common compound: 2675-89-0, name is 2-Chloro-N,N-dimethylacetamide, belongs to amides-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.
EXAMPLE 18; N,N-Dimethylaminocarbonylmethyl 3-Aminosulfonyl-5-butylamino-4- phenoxybenzoate (Bumetanide N,N-Dimethylglycolamido Ester); [0481] Bumetanide (1.2g, 3.29 mmol) was dissolved in dimethylformamide (DMF, 10 mL) and 2- chloro-N,N-dimethylacetamide (410 muL, 3.9 mmol) was added followed by triethylamine (0.70 mL) and sodium iodide (545 mg, 3.6 mmol). The reaction was heated to 50C for 10 hours, TLC and LC/MS indicated the reaction was complete. The solvent was removed under reduced pressure and the residue was dissolved in ethyl acetate and washed with saturated sodium bicarbonate, water, and brine and dried over anhydrous magnesium sulfate. The ethyl acetate was removed under reduced pressure and the product was purified via flash chromatography on silica gel to yield 685 mg (60%) of pure N,N- dimethylaminocarbonylmethyl 3-aminosulfonyl-5-butylamino-4-phenoxybenzoate.
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-Chloro-N,N-dimethylacetamide, other downstream synthetic routes, hurry up and to see.
