2-(1,3-Benzothiazol-2-yl)guanidine

2-(1,3-Benzothiazol-2-ylsulfanyl)-N-(2-methylphenyl)acetamide

In the title mol-ecule, C(16)H(14)N(2)OS(2), the benzene ring and the benzo[d]thia-zole mean plane form a dihedral angle of 75.5 (1)°. The acetamide group is twisted by 47.7 (1)° from the attached benzene ring. In the crystal, mol-ecules related by translation along the a axis are linked into chains through N-H⋯O hydrogen bonds.

Ethyl 2-[4-(1,3-benzothiazol-2-yl)­anilino]acetate

In the title compound, C(17)H(16)N(2)O(2)S, the dihedral angle between the benzothia-zole ring system and the benzene ring is 1.20 (2)°. The substituted amino substituent is in an extended conformation with an N-C-C-O torsion angle of 179.4 (3)°. In the crystal structure, pairs of mol-ecules are connected by inter-molecular N-H⋯O and weak C-H⋯O hydrogen bonds, forming centrosymmetric dimers.
