Abstract
The title compound, C15H22N2O2, is monoclinic:P21,a=10.876(2),b=8.620(2),c=7.390(2) Å, β=99.2(2)°,Z=2. TheA/B ring junction configuration isquasi-trans, and theC/D junction istrans. RingA has a conformation intermediate between sofa and half-chair; ringsB,C, andD are in chair, boat, and distorted chair conformations, respectively.
