Abstract
The title compound, C21H17NS, was synthesized via the reaction of 5-(2-phenyleth-1-ynyl)thiophene-2-carbaldehyde and 3,4-dimethylaniline using ammonium bifluoride (NH4HF2) as an acid catalyst in methanol. The molecule has three aryl rings: a phenyl (A), a thiophene (B), and a dimethylbenzene ring (C). The dihedral angles between the mean planes defined by these individual rings are 14.88 (6)° for A/B and 43.93 (4)° for B/C.
