実験手順

The first portion of purified Oxycodone base lot P (13.56 g, 43.0 mmol) was dissolved (in 80-mL beaker over 15 minutes) in a mixture of water (13 mL) and acetic acid (3 mL). Hydrochloric acid (10.41 mol/kg, 5.0 g, or 51.6 mmol) was added to the solution over 5 minutes. Stirring was continued for another 40 minutes and IPA (55 mL) was added over 15 minutes. Stirring was continued for another 30 minutes. Precipitated product was filtered off, washed on filter with IPA (2×20 ml) and acetone (2×20 mL), dried on filter providing 14.74 g oxycodone HCl (39.86 mmol, 93% yield on OC base purified) lot Q.
