چکیده
In the crystal structure of the title compound, C(26)H(32)ClNO(8), the piperidine ring is in a twist-chair conformation, with puckering parameters Q = 0.655 (4) Å, θ = 93.1 (1) and ϕ = 254.4 (3)°. The ortho C atoms of the piperidine ring deviate from the plane defined by the remaining ring atoms by 0.380 (3) and -0.250 (3) Å.
