-
, (2015/06/24)
Synthetic methods are provided for preparation of oxycodone and salts thereof with an improved impurity profile. Thebaine is converted to 14-hydroxycodeinone sulfate intermediate to minimize a 7,8-dihydro-8,14-dihydroxycodeinone impurity. Efficient methods for conversion of oxycodone base to oxycodone hydrochloride are provided to minimize 14-hydroxycodeinone impurity in the final product.

A METHOD FOR PREPARING OXYCODONE
-
Page/Page column 31; 32, (2014/02/16)
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 6α-oxycodol in an amount ≤ about 0.800 area % as determined by HPLC.
PROCESS FOR THE SYNTHESIS AND PURIFICATION OF OXYCODONE
-
, (2012/01/15)
A method of preparing oxycodone includes forming 14-hydroxycodeine by reduction of 14-hydroxycodeinone and rearrangement of the 14-hydroxycodeine to form the oxycodone. During the reduction step, the ketone group of an undesirable contaminant precursor, 8, 14-dihydroxy-7,8-dihydrocodeinone, is reduced to a hydroxyl group thus forming a triol. This triol is substantially inert with respect to reforming 14- hydroxycodeinone and can be readily separated from oxycodone.
