Steps:

2.8.A 3-[(N-normorphino)acetamindo]-2,2,5,5-tetramethylpyrrolidinyl-1-oxyl
A. Morphine (8.66 g) was acetylated with acetic anhydride (32 g) and pyridine (25 g) at room temperature overnight. After removal of the solvents by azeotroping with benzene, the residue was dissolved in dichloromethane, washed with saturated sodium chloride solution, 2.5% sodium chloride solution, 2.5% sodium carbonate solution, 2N-hydrochloric acid, and finally, saturated sodium chloride solution. Evaporation of the dichloromethane after drying over anhydrous sodium sulfate afforded heroin in a solid state (10.59 g) mp 169°-173°.
