2-(4-Methylphenyl)benzothiazole (cas: 16112-21-3) belongs to thiazole derivatives. The thiazole ring is notable as a component of the vitamin thiamine (B1). Electrophilic attack at nitrogen depends on the presence of electron density at nitrogen as well as the position and nature of substituent linked to the thiazole ring.Synthetic Route of C14H11NS

Chitosan-SO3H: a green approach to 2-aryl/heteroaryl benzothiazoles under solvent-free conditions at room temperature was written by Bathula, Surendra Bose;Khagga, Mukkanti;Venkatasubramanian, Hariharakrishnan. And the article was included in Asian Journal of Chemistry in 2018.Synthetic Route of C14H11NS This article mentions the following:

An efficient green protocol was developed for the synthesis of 2-aryl/heteroaryl benzothiazoles by intramol. cyclocondensation of 2-mercaptoaniline with aryl/heteroaryl aldehydes using chitosan-SO3H as an efficient biocompatible and reusable heterogenous solid acid catalyst in presence of air under solvent free conditions at room temperature In the experiment, the researchers used many compounds, for example, 2-(4-Methylphenyl)benzothiazole (cas: 16112-21-3Synthetic Route of C14H11NS).
