Abstract
Process for obtaining naloxone from thebaine.- essentially characterized in that it consists of separately obtaining dihydroxydeinone starting from thebaine, subsequently breaking the phenolic ether of the dihydroxydeinone by means of pyridine salts of a strong acid and in a solvent such as dimethylsulfoxide, demethylating the oxycodone, obtaining as an intermediate element oxymorphone, subsequently treating said oxymorphone with alkyl chloroformates, protecting the phenolic group and eliminating the methyl linked to the nitrogen by transformation to an intermediate derivative of the urethane type, obtaining the nordihydroxymorphinone by hydrolysis of the derivative. Intermediate, subsequently producing the alkylation of the nitrogen by unsaturated alkyl halides, obtaining naloxone in basic and solid state, said naoloxone being subjected to a washing and subsequent crystallization, which gives rise to a pure product which is the starting base for the tion of denaloxone salts.
