A process is described for the preparation of N,N-diisopropyl-3-(2-hydroxy-5-methylphenyl)-3-phenyl-propaneamine comprising substitution of the sulfonyloxy group of the compound of the formula in which the substituents R and R″ have the meanings stated in the description, in a solvent comprising an ionic liquid, to yield the tertiary amine of the formula and the subsequent deprotection thereof.
摘要:
The present invention relates to a mild and industrially applicable process for preparing sulfinyl derivatives of Formula (II), useful as inhibitors of gastric acid secretion, comprising the selective oxidation of the corresponding sulfides of Formula (I), as represented in scheme (I) and (II) in which said oxidation is performed with hydrogen peroxide in the presence of low amounts of a rhenium compound as catalyst, at a temperature from 0° C. to room temperature.
摘要:
The present invention relates to a purifying process for phosphatidylserine, the latter being prepared by trans-phosphatidylation of phosphatidylcholine with serine in presence of the enzyme D-phospholipase and containing as impurities hydrophilic compounds, proteins and inorganic salts.
摘要:
A process for the preparation of highly pure deacylated glycerophosphorylcholine, glycerophosphorylethanolamine and glicerophosphorylserine starting from mixtures of the corresponding acylated derivatives.The process according to the invention is characterized in that the deacylation reaction, by means of alcoholysis, and the fractionation are carried out in a single step in a reactor containing a basic ion-exchange resin.
