Reaction Steps
To obtain the corresponding 4-methylamino compound, a suspension of (20S)-4-chloro-21-hydroxy-20-methylpregn-4-en-3-one acetate in methanol was mixed with 40% aqueous methylamine and refluxed for 30 minutes. Additional 40% aqueous methylamine was added and refluxing was continued for another 30 minutes. The solvent was then evaporated and the residue was purified as described above for the 4-amino compound to give (20S)-4-(methylamino)-21-hydroxy-20-methylpregn-4-en-3-one.
