Procedure

To a 200 mL flask, dried oripavine (10.00 g, 95% wt/wt %) was dissolved in HOAc/H2O (1:4, 100 mL) and cooled to 5° C. to 10° C. Peroxyacetic acid, CH3CO3H, (9.1 mL, 32% wt/wt %) was added over 3 minutes and the reaction mixture was stirred at 5° C. to 10° C. for 30 minutes. HPLC data showed that the reaction was completed. The reaction mixture was allowed to warm to 25° C. for 30 minutes. H2C2O4 (3.0 g) was added to the reaction mixture, and was stirred at room temperature for 30 minutes and then heated to 50° C. for 30 minutes. The solution was assayed by HPLC and >99% conversion was observed.
