2-Amino-4-(4-chlorophenylthio)-5-phenyl-6-(1-piperidyl)pyrimidine

D. E. Lynch and I. McClenaghan

Abstract: The structure of the title compound, C₂₁H₂₁ClN₄S, comprises a fully substituted pyrimidine ring that packs in a 2-aminopyrimidine-type hydrogen-bonded polymer chain. However, hindrance from the chlorophenylthio group, in turn altered by the presence of the phenyl ring, creates a convoluted hydrogen-bonded chain. The dihedral angle between the thiophenyl and pyrimidine rings is 70.10  (7)°, while the dihedral angle between the phenyl and pyrimidine rings is 56.14  (8)°. Neither the S nor the Cl atoms is involved in the hydrogen-bonding network.
