The chemistry of heterocycles has received a great deal of attention in recent times due to their importance, and among these heterocycles is benzothiazolinone, which has received a great deal of attention due to its biological, pharmacological [1], [2], and agricultural [3] benefits.
Schiff bases, which are molecules whose structure contains imine functions (C=N), have also been the subject of constant attention and development due to their different biological properties [4], [5].
In this context, we synthesized an imine-benzothiazolinone molecule (E)-3-methyl-6-((naphthalen-1-ylimino)methyl)benzo[d]thiazol-2(3H)-one according to an environmentally friendly green chemistry approach using ultrasound in ethanol, which enabled the target compound to be recovered in high yield in a short and pure time without the need for purification techniques.
The structure of the compound was confirmed by IR, 1H NMR and 13C NMR spectroscopic methods. Additionally, a study was conducted to examine the synthetic compound's pharmacological ADME properties based on lipinski's rule of five , revealing favorable drug-likeness characteristics and supporting its potential for further pharmaceutical development." .
