2-[(1R,3S)-6,7-Dimeth-oxy-1-phenyl-1,2,3,4-tetra-hydro-isoquinolin-3-yl]-4-phenyl-1,3-thia-zole.

In the title compound, C(26)H(24)N(2)O(2)S, the dihedral angle between the thia-zole ring and the adjacent phenyl ring is 3.02 (15)°. The N-containing six-membered ring of the tetra-hydro-isoquinoline unit adopts a half-chair conformation. The dihedral angle between the least-squares plane of the tetra-hydro-isoquinoline ring system and its nearest phenyl ring is 76.90 (13)°. No classical hydrogen bonds nor π-π inter-actions were found in the crystal structure.
