4-(2,4,6-Trimethyl-benz-yl)-1,3-thia-zol-2-amine
Abstract:
The methyl-ene C atom in the title compound, C(13)H(16)N(2)S, is connected to a five-membered thia-zole ring and a mesityl substituent. The rings are aligned at 75.4 (1)°. The amino substitutent inter-acts with the ring N atom of an adjacent mol-ecule by an inter-molecular N-H⋯N hydrogen bond, generating a helical chain running along the b axis.
