Reaction Steps

The free base of oxycodone was prepared from its hydrochloride salt by the following method: Oxycodone hydrochloride was dissolved in water and sodium carbonate was added in the amount required to neutralize hydrochloric acid. Methylene chloride was added in order to extract the formed oxycodone free base. The obtained organic layer was dried over sodium sulfate and methylene chloride was evaporated using rotary evaporator. The obtained oxycodone free base was purified by crystallization.
