【 摘 要 】

In the title compound, C19H25NO2, the pyrrolidine ring adopts an envelope form, with the spiro C atom as the flap, while the cyclo­hexane ring shows a chair form. A weak intra­molecular C—H⋯O inter­action supports the mol­ecular conformation, generating an S(6) ring motif. In the crystal, pairs of C—H⋯O inter­actions connect the mol­ecules into inversion dimers with an R22(16) ring motif. The dimers are linked by a second pair of C—H⋯O inter­actions, enclosing an R42(12) ring motif, into a tape structure along the b axis.
