Abstract

Abstract 4-(N, N-Dimethylamino) pyridine is found to be an efficient catalyst for the synthesis of benzothiazoyl carbaimide derivatives using 2-aminobenzothiazoles and phenylisothiocyanates, which on treatment with ionic liquid [bbim][Br 3] at 70 C afforded exclusive formation of N-bis-benzothiazole derivatives in good yield.
