الإجراء التجريبي

To a solution of oxycodone-freebase (1.0 eq) in tetrahydrofuran (THF) (10 ml/mmol) was added LiN(TMS)2 (3.5 eq). After 5 minutes, Boc-Phe-OSu (3.5 eq) was added. The reaction was stirred at ambient temperatures for 18 hours, quenched with water and solvents removed. Crude protected product was purified using reverse-phase HPLC. Deprotection occurred with 4N HCl in dioxane (20 ml/mmol) to obtain Phe-Oxycodone.
