With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.179087-93-5,2-(4-((2,4-Dioxothiazolidin-5-yl)methyl)phenoxy)acetic acid,as a common compound, the synthetic route is as follows.
Examples (Example 1) 4-[(2,4-Dioxothiazolidin-5-yl)methyl]phenoxyacetyl chloride Thionyl chloride (170 mg, 1.34 mmol) and then pyridine (1 drop) were added to a suspension of 4-[(2,4-dioxothiazolidin-5-yl)methyl]phenoxyacetic acid (220 mg, 0.78 mmol) in dichloromethane (10 ml) at room temperature, and the mixture was refluxed for 3.5 hours. The resulting solution was concentrated under reduced pressure to obtain about 250 mg of the gummy target compound. Nuclear magnetic resonance spectrum (400 MHz, DMSO-d6) delta (ppm): 3.05 (1H, dd, J = 9.0 Hz, J = 14.1 Hz, CH2CH), 3.31 (1H, dd, J = 4.1 Hz, J = 14.1 Hz, CH2CH), 4.64 (2H, s, CH2O), 4.87 (1H, dd, J = 4.1 Hz, J = 9.0 Hz, CH2CH), 6.85 (2H, d, J = 8.6 Hz, aromatic), 7.16 (2H, J = 8.6 Hz, aromatic), 12.02 (1H, s, NH).
The synthetic route of 179087-93-5 has been constantly updated, and we look forward to future research findings.
