ABSTRACT
The title compound, C10H8N4O2S, was synthesized from furoyl isothio-cynate and 2-amino-pyrimidine in dry acetone. The two N-H groups are in an anti conformation with respect to each other and one N-H group is anti to the C=S group while the other is syn. The amide C=S and the C=O groups are syn to each other. The mean plane of the central thio-urea fragment forms dihedral angles of 13.50â
(14) and 5.03â
(11)° with the furan and pyrimidine rings, respectively. The dihedral angle between the furan and pyrimidine rings is 18.43â
(10)°. The mol-ecular conformation is stabilized by an intra-molecular N-Hâ¯N hydrogen bond generating an S(6) ring motif. In the crystal, mol-ecules are linked by pairs of N-Hâ¯N and weak C-Hâ¯S hydrogen bonds to form inversion dimers.
