Mettey, Yvette,Michaud, Sabine,Vierfond, Jean Michel
, p. 1001 - 1006 (2007/10/02)
A one-pot synthesis of 2-substituted phenylbenzothiazoles is achieved when 2-aminobenzenethiol is treated with an excess of sodium hydride and aromatic nitriles in THF.This method allows to obtain substituted products (F, CF3, Cl or OCH3) in each ortho, m
