With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.151038-94-7,6-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)hexanehydrazide 2,2,2-trifluoroacetate,as a common compound, the synthetic route is as follows.
[00250] Acetoxycisplatin(4-acetylphenyl)carboxylate (178 mg, 0.341 mmol, 1 equiv) was dissolved in DMF (0.05 M, 6.8 mL) and treated with 6-(2,5-dioxo-2,5- dihydro-1 H-pyrrol-1 -yl)hexanehydrazide TFA salt (139 mg, 0.409 mmol, 1 .2 equiv). The reaction mixture was stirred at room temperature for 5 hours. MTBE was added to the reaction mixture until a suspension was obtained and a yellow solid was filtered to afford compound 17 (159 mg, 64%, 97% pure). 1H NMR (500 MHz, DMF-d7) delta 10.48 (s, 0.3H), 10.40 (s, 0.6H), 7.97-7.92 (m, 2H), 7.91 -7.86 (m, 2H), 7.24-6.77 (m, 6H), 7.02 (s, 2H), 3.50-3.44 (m, 2H), 2.77-2.72 (m, 1 .4H), 2.44-2.38 (m, 0.6H), 2.40 (s, 2H), 2.37 (s, 1 H), 1 .94 (s, 3H), 1 .73-1 .64 (m,2H), 1 .63-1 .54 (m, 2H), 1 .42-1 .29 (m, 2H); HPLC-MS 98%, m/z for CziHzgC NsOyPt [(M+H)+] = 730.2.
151038-94-7, 151038-94-7 6-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)hexanehydrazide 2,2,2-trifluoroacetate 23509306, apyrrolines compound, is more and more widely used in various fields.
