Reaction of 5α‐cholestan‐6‐one oxime (1), its 3β‐acetoxy and 3β‐chloro analogs, 2 and 3, respectiveley, with ClCH2CH2NH2⋅HCl in presence of MeONa afforded 6‐[(2‐aminoethoxy)imino]‐5α‐cholestane (4), 3β‐acetoxy‐6‐[(2‐aminoethoxy)imino]‐5α‐cholestane (5), and 6‐[(2‐aminoethoxy)imino]‐3β‐chloro‐5α‐cholestane (6), respectively. The structures of newly synthesized compounds have been established on the
