Abstract
Prednisone was prepared by condensation,reduction and nitroustion from prednisone acetate,prednisone acetate through condensation reaction protected carbonyl of C3 and C20 positions,then hydrogenation over NaNH4,gives C11-OH of function,which stirred 6NHcl in water to pH2-3,affords white solids.Study on control methods at quality of medium reference TLC accetapble standard by B.P.98.
