4-Cyano-N-ethylspiro[chromene-2,4′-piperidine]-1′-carboxamide
The title compound, C17H19N3O2, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In both mol-ecules, the pyran ring has a twisted conformation ((5)S4), with Q = 0.301 (3) Å, θ = 116.7 (6) and ϕ= 213.6 (7)° for mol-ecule A, and Q = 0.364 (2) Å, θ = 113.7 (3) and ϕ = 213.0 (4)° for mol-ecule B. In mol-ecule B, the terminal ethyl group is disordered over two orientati...
