Abstract

A variety of 2-aminobenzothiazoles were synthesized by using 2-chloroanilines and dithiocarbamates through a tandem approach in the presence of Pd(PPh3)4 and t-BuOK. The facile and efficient protocol enabled the reaction to proceed at a good rate with excellent yields.

Key words

potassium tert-butoxide - palladium - chloroloaniline - aminobenzothiazole - tandem
