3622-35-3, Benzo[d]thiazole-6-carboxylic acid is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Benzothiazole-6-carboxylic acid (0.0717 g, 0.582 mmol) and 1-hydroxybenzotriazole (118 mg, 0.874 mmol) were dissolved in N,N-dimethylformamide (8 mL, 100 mmol). N-(3-dimethylaminopropyl)-N’-ethylcarbodiimide hydrochloride (0.168 g, 0.874 mmol) was added and the reaction was stirred at rt for 20 min. Methyl-[4-(quinolin-2-ylmethoxy)-phenyl]-amine (0.153 g, 0.582 mmol) was added followed by triethylamine (0.244 mL, 1.75 mmol). The reaction was stirred at room temperature for 20 h. H2O (20 mL) was added to the reaction and the mixture was extracted with ethyl acetate (40 mL * 3). The combined organic phases were washed with satd aq NaHCO3 (40 mL), dried with magnesium sulfate, filtered and evaporated. The crude product was purified using column chromatography. The product fractions were combined and evaporated and the residue crystallised from ethyl acetate/heptane to yield the title compound as an off white solid (20% yield). 1H NMR: (600 MHz, CDCl3) delta 9.00 (s, 1H), 8.17 (d, J = 8.7 Hz, 1H), 8.05 (d, J = 8.7 Hz, 1H), 8.01 (s, 1H), 7.87 (d, J = 8.7 Hz, 1H), 7.83 (d, J = 8.2 Hz, 1H), 7.73 (dt, J = 1.4 Hz, J = 7.4 Hz, 1H), 7.59-7.53 (m, 2H), 7.35 (d, J = 8.2 Hz, 1H), 6.98 (d, J = 8.4 Hz, 2H), 6.86 (d, J = 8.8 Hz, 2H), 5.29 (s, 2H), 3.49 (s, 3H). [M+H+]: 426.1., 3622-35-3
3622-35-3 Benzo[d]thiazole-6-carboxylic acid 601670, athiazole compound, is more and more widely used in various fields.
