With triethylamine; In tetrahydrofuran; at 0 - 25℃; for 1h; General procedure: Chloroacetyl chloride(33 mmol, 2.63 mL) was added dropwise with stirring to a mixtureof triethylamine (33 mmol, 4.63 mL) and 2-aminobenzothiazole oraniline derivative (30 mmol) in THF (100 mL) at 0 C. After thecompletion of dropping, the mixturewas allowed to stir for 1 h. Thesolvent was evaporated under reduced pressure. The residue waswashed with water to remove trimethylamine hydrochloride, driedand recrystallized from EtOH [59,60].
With triethylamine; In tetrahydrofuran; at 0 - 25℃; for 1h; General procedure: Corresponding benzo[d]thiazol-2-amine (3 and 4) (0.025 mol) and triethylamine (0.030 mol,4.24 mL) were dissolved in THF (50 mL). This mixture was kept on an ice bath andchloroacetyl chloride (0.030 mol, 2.37 mL) in THF (10 ml) was added dropwise with constantstirring. After this stage, the content was allowed to stir for an additional 1 h at roomtemperature. THF was evaporated, the raw product was washed with water, dried andrecrystallized from ethanol.2,3
