2-Dicyclo­hexyl­amino-3-phenyl-56-di­hydro-8H-thio­pyrano4′3′:45thieno23-dpyrimidin-4(3H)-one

摘要

In the title compound, C27H33N3OS2, the dihedral angle between the two fused rings of the thieno[3,2-d]pyrimidine system is 3.73 (9)°. The phenyl ring is twisted with respect to the pyrimidine ring [dihedral angle = 71.60 (10)°] and the thio­pyran ring shows an envelope conformation with the S atom as the flap. An intra­molecular C—H⋯O inter­action occurs. In the crystal, inversion dimers linked by pairs of C—H⋯O hydrogen bonds occur.
