In the title compound, C13H12N2OS, which was obtained from the condensation reaction of 2-aminobenzenethiol with isocyanatobenzene, the benzene rings are inclined to one another by 83.5 (1)° and a short intramolecular C—H...O contact is observed. In the crystal, molecules are linked by N—H...O and N—H...N hydrogen bonds, generating (001) sheets.
