1-Methyl-3-phenyl­thio­urea

The title compound, C(8)H(10)N(2)S, was prepared by reaction of methyl­amine solution, KOH and phenyl-iso­thio­cyanate in ethanol. It adopts a syn-Me and anti-Ph conformation relative to the C=S double bond. The dihedral angle between the N—C(=S)—N thio­urea and phenyl planes is 67.83 (6)°. In the crystal, the mol­ecules centrosymmetrical dimers by pairs of N(Ph)—H⋯S hydrogen bonds. The dimers are linked by N(Me)—H⋯S hydrogen bonds into layers parallel to (100).
