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.
[00393] A solution of FK506 (1) (0.1 g, 124.4 mumol), 6-maleiimidocaproic hydrazide trifluoroacetate (2) (0.126 g, 373.2 mumol) and trifluoroacetic acid (catalytic, 1 muL) in anhydrous methanol (5 mL) was stirred at room temperature for 36 h. The reaction was monitored by thin layer chromatography that showed almost complete disappearance of the starting material. [TLC solvent system-dichloromethane (95): methanol (5), Rf=0.3]. The reaction mixture was concentrated to dryness and dissolved in ethyl acetate (20 mL). The organic layer was washed with water and 10% sodium bicarbonate solution and then dried over sodium sulfate, filtered and concentrated. The residue was purified by column chromatography using dichloromethane (96): methanol (4) as eluent to give the hydrazone 3 (0.116 g, 92%).
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.
