The thiazolidine compound, cas is 7025-19-6 name is 3-(4-Oxo-2-thioxothiazolidin-3-yl)propanoic acid, mainly used in chemical industry, its synthesis route is as follows.
7025-19-6, [00161] To a solution of 2,3-dimethoxybenzaldehyde 1 (200 mg, 1.20 mmol) and 3-(4- oxo-2-thioxothiazolidin-3-yl)propanoic acid 2 (247 mg, 1.20 mmol) in glacial acetic acid (4 mL) was added sodium acetate (197 mg, 2.41 mmol) and the reaction was heated at 90 C for 6 h. After the completion of reaction (as monitored by LCMS) the reaction mixture was poured into ice cooled water, stirred for 15 mm and the solid precipitated out was filtered, washed with diethyl ether and dried in vacuo to afford 235 mg (55% yield) of NADi-241 as yellow solid. ?H NMR (400 MHz, DMSO-d6) 12.50 (s, 1 H), 7.89 (s, 1 H), 7.25 (d, J = 1.87 Hz, 2 H), 7.06 (dd, J = 3.74, 5.62 Hz, 1 H), 4.20 – 4.26 (m, 2 H), 3.86 (s, 3 H), 3.82 (s, 3 H), 2.61 – 2.66 (m, 2 H) ; MS (ES+): mlz = 353.90 [M+Hj; HPLC = 99.28%.
With the rapid development of chemical substances, we look forward to future research findings about 7025-19-6
