N-Benzyl­thieno[3,2-d]pyrimidin-4-amine

The title compound, C(13)H(11)N(3)S, crystallizes with two independent mol­ecules in the asymmetric unit. The two mol­ecules are geometrically very similar and differ mainly in a spatial orientation of the benzene and thieno[3,2-d]pyrimidine ring systems [dihedral angles = 69.49 (4) and 79.05 (3)°]. The nine-membered thieno[3,2-d]pyrimidine moieties have a planar conformation (r.m.s. deviations = 0.020 and 0.012 Å). In the crystal, mol­ecules are linked through N—H⋯N, N—H⋯C and C—H⋯π non-covalent contacts into chains along the c axis, while neighbouring chains are connected via C—H⋯N inter­actions.
