  • Publication number: 20160176887
    Abstract: A process for preparing a compound of formula (3), includes the steps of: (a) providing an aqueous acidic solution including a compound of formula (1) and, as an impurity, a compound of formula (2); and (b) treating the aqueous acidic solution of step (a) such that the compound of formula (2) dehydrates to form a compound of formula (1) which is reduced to form an aqueous acidic solution of the compound of formula (3), the treating step (b) being carried out at one or more temperatures greater than ambient in the presence of a hydrogenation catalyst and hydrogen gas; and wherein for the compounds of formulae (1), (2) and (3): i) R1 is —OH, R2 is —OH and R3—H; or ii) R1 is —OCH3, R2 is —H and R3—CH3; or iii) R1 is —OH, R2 is —H and R3—CH3; or iv) R1 is —OCH3, R2 is —H and R3—H; or v) R1 is —OH, R2 is —H and R3—H; or vi) R1 is —OCH3, R2 is —OH and R3—H.

  • Patent number: 8916707
    Abstract: The present invention provides a process for preparing an oxycodone acid adduct, said process comprising hydrogenating an aqueous solution of 14-hydroxycodeinone and an acid to form a solution of the oxycodone acid adduct, wherein the hydrogenation is carried out at one or more temperatures greater than ambient temperature in the presence of a hydrogenation catalyst and hydrogen gas, wherein the solution of oxycodone acid adduct comprises 6?-oxycodol in an amount ?about 0.800 area % as determined by HPLC.
    Type: Grant
