(E)-N'-{7-Meth-oxy-spiro-[chromeno[4,3-d]thia-zole-4,1'-cyclo-hexa-n]-2-yl}-N,N-dimethyl-acetimidamide.

In the chromenothia-zole ring system of the title mol-ecule, C(20)H(25)N(3)O(2)S, the pyran ring is in a half-chair conformation. The dihedral angle between the thia-zole and benzene rings is 14.78 (6)°. The cyclo-hexane ring is in a chair conformation. The crystal structure is stabilized by weak inter-molecular C-H⋯N and C-H⋯O hydrogen bonds.
