| Summary: | <i>N</i>-(Anthracen-9-ylmethyl)-<i>N</i>-methyl-2-(phenylsulfonyl)ethanamine <b>3</b> has been synthesized via the aza-Michael addition approach by reaction of the corresponding amine with the vinyl sulfone derivative under microwave conditions. The structure of the aza-Michael product <b>3</b> is elucidated by X-ray crystallography. The study of molecular packing by employing the Hirshfeld analysis indicates that the percentages of O…H, C…H and H…H contacts are 16.8%, 34.1% and 48.6%, respectively, where the O...H hydrogen bonds have the characteristics of short and strong contacts while the C...H contacts are considered weak. Density functional theory (DFT) investigations show that the aza-Michael product <b>3</b> is polar with a net dipole moment of 5.2315 debye.
