Abstract: The title compound, C10H8N4O2S, was synthesized from furoyl isothio­cynate and 2-amino­pyrimidine 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 thio­urea fragment forms dihedral angles of 13.50 (14) and 5.03 (11)° with the furan and pyrimidine rings, respectively. The dihedral angle between the furan and pyrimidine rings is 18.43 (10)°. The mol­ecular conformation is stabilized by an intra­molecular N-H...N hydrogen bond generating an S(6) ring motif. In the crystal, mol­ecules are linked by pairs of N-H...N and weak C-H...S hydrogen bonds to form inversion dimers.
