5-Acetyl-3-amino-4-(4-meth--oxy-phen-yl)-6-methyl-thieno[2,3-b]pyridine-2-carbo-nitrile

摘要

The asymmetric unit of the title compound, C18H15N3O2S, comprises two independent mol-ecules, which differ primarily in the orientations of the acetyl and?p-anisyl substituents, each being rotated in opposite directions from the mean plane of the pyridine ring. The major feature of the mol-ecular packing is the formation of a two-dimensional network parallel to the (110) plane, being mediated by amine-N—H?O(carbon-yl) hydrogen bonds involving one amine H atom of each independent mol-ecule. The remaining amine-H atoms form significantly weaker N—H?O(meth-oxy) inter-actions.
