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—HN and weak C—HS hydrogen bonds to form inversion dimers.
