YieldReaction ConditionsOperation in experiment
22% With boron tribromide In dichloromethane at -78 - 0℃; for 1 h; Inert atmosphere A 1N boron bromide methylene chloride solution (8.4 ml, 8.40 mmol) was added to a methylene chloride solution (10 ml) of 6-methoxy-2-methylbenzothiazole (500 mg, 2.79 mmol), at -78°C, under nitrogen stream, and stirring was carried out at 0°C for 1 hour. Water was added to the reaction solution, followed by extraction with methylene chloride. The extract was washed sequentially with a saturated aqueous sodium hydrogencarbonate solution and water, and then dried over anhydrous sodium sulfate. The organic layer was concentrated and the resulting residue was purified by a medium-pressure preparative liquid chromatograph (manufactured by Yamazen Corporation, W-Prep 2XY) to afford 2-methyl-1,3-benzothiazol-6-ol (103 mg, yield 22percent) as a colorless oil. 1H-NMR (CDCl3, 400 MHz) δ: 7.66 (1H, d, J=8.8 Hz), 7.23 (1H, d, J=2.4 Hz), 6.94 (1H, dd, J=8.8 Hz, 2.4 Hz), 2.74 (3H, s). MS (ESI, m/z): 166 (M+H)+.
