With bromine; In acetic acid; at 25℃; for 12h; | General procedure: An appropriate aniline derivative (1 and 2) (0.04 mol) and KSCN (0.16 mol, 15.5 g) weredissolved in glacial acetic acid (70 mL). A solution of bromine (0.04 mol, 2.05 mL) in glacialacetic acid (10 mL) was added dropwise. The mixture was stirred for 12 h. The solution wasfiltered and neutralized by ammonia (33%). The precipitate was filtered off, dried andrecrystallized from ethanol.1 |

22.00% | With TEA; In dichloromethane; at 20℃; | 2-Chloro-N-(5,6-dimethoxybenzo[d]thiazol-2-yl)acetamide (Compound 53) To the reaction mixture of <strong>[6294-52-6]5,6-dimethoxybenzo[d]thiazol-2-amine</strong> (50 mg, 0.238 mmol), TEA (0.100 mL, 0.713 mmol) in DCM (1 mL) was added 2-chloroacetyl chloride (0.023 mL, 0.285 mmol) at room temperature. Overnight, concentration and purification on combiflash (4 g, MeOH/DCM) gave 2-chloro-N-(5,6-dimethoxybenzo[d]thiazol-2-yl)acetamide (15 mg, 0.052 mmol, 22.00% yield). 1HNMR (400 MHz, CDCl3), 9.73 (s, 1H), 7.26 (s, 1H), 7.25 (s, 1H), 4.30 (s, 2H), 3.969s, 6H) ESI-MS: m/z 286.94 (M+H)+ |

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 |
