[0071] Synthesis of 2-L-lysine-(2,6-diisopropyl-phenyl-)carbonic anhydride dihydrochloride (compound 1)

[0072]

[0073] Compound 1

[0074] Under water bath conditions, propofol (2.6mmol, 0.46g) was added to anhydrous dichloromethane (30ml), cooled to -5°C, triphosgene (0.9mmol, 0.27g) was added, and under temperature control, dropwise Add triethylamine (2.6 mmol, 0.26 g), slowly warm up to room temperature, and stir for 1 hour. then add N α -tert-butoxycarbonyl-N ε -tert-butoxycarbonyl-lysine (2.2mmol, 0.76g), triethylamine (2.2mmol, 0.22g), stirred overnight at room temperature. The reaction was monitored by HPLC until the raw material was completely reacted. Concentrate, add 4M HCl / dioxane solution (20ml), stir and react at room temperature for 1h. The solvent was evaporated under reduced pressure, the insoluble matter was washed by adding n-hexane, and filtered to obtain a white solid, which was recrystallized from ether / n-hexane to obtain 0.61 g of compound 1 ...

Description

technical field [0001] The present invention relates to water-soluble derivatives of carbonic acid diester of amino acid and propofol and their non-toxic pharmaceutically acceptable salts, their preparation method, their pharmaceutical composition and their use as anesthetics. Background technique [0002] Propofol (chemical name: 2,6-diisopropylphenol, also known as propofol), is a quick-acting, short-acting systemic intravenous anesthetic, with the characteristics of fast onset and quick recovery, and no accumulation , has been widely used clinically. However, due to its poor water solubility, it is mainly used clinically in fat emulsion. The emulsion of propofol has poor physical stability, and it is easy to cause pain at the injection site and inflammatory reaction during clinical use, and it is difficult to be compatible with other preparations. [0003] [0004] Propofol Chemical Structure [0005] In December 2008, the U.S. FDA approved a water-soluble derivativ...
