Procedure

The crude Oxymorphone Base (267.7 g wet, 180.1 g dry basis) was transferred back to a clean 3000 mL reaction vessel and 1-propanol (321.6 g) was charged. The slurry was heated to 90±3° C. and stirred for 1.5 h. The temperature was lowered to 25±5° C. and stirred for 1 h. The batch was further cooled to 10±5° C. and stirred 1 h. The product was collected by filtration washing the cake with 1-propanol (10±5° C., 2×48.2 g) then drying under vacuum at 55±5° C. to give Oxymorphone Base (167.8 g, 83.3% yield, 99.9 area %, 6α-oxymorphol 0.11 area %, 6β-oxymorphol not detected).
