4318-42-7, 1-Isopropylpiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,4318-42-7

To a vial was added 4-fluoronitrobenzene (1.41 g, 1.06 mL, 0.01 mo1) , N,N-diisopropylethylamine (1.92 mL, 0.011 mmol), isopropylpiperazine (1.41g, 0.011 mmol), and N1N- dimethylformamide (10 mL) . Mixture was heated at 1000C for 48 h in a sealed tube. The reaction mixture wag cooled to room temperature and concentrated. The residue was purified via silica gel column chromatography (gradient elution with 0 to 10percent methanol in dichloromethane) to afford 1-isopropyl- 4- (4-nitrophenyl)piperazine.

4318-42-7 1-Isopropylpiperazine 78013, apiperazines compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4318-42-7,1-Isopropylpiperazine,as a common compound, the synthetic route is as follows.,4318-42-7

Step D. [2-(3,4-Dichloro-phenoxy)-5-(4-isopropyl-piperazine-1- carbonvD-benzvH-methyl-carbamic acid tert-butyl ester.; To a solution of [5- bromo-2-(3,4-dichloro-phenoxy)-benzyl]-carbamic acid tert-butyl ester (327.0 mg, 0.71 mmol) in THF (2 ml.) were added DBU (0.30 ml_, 2.0 mmol), 1- isopropyl piperazine (0.30 ml_, 2.5 mmol), Hermann’s catalyst (31 .9 mg, 0.034 mmol), tri-f-butylphosphium tetrafluoroborate (26.4 mg, 0.091 mmol), and Mo(CO)6 (21 1.0 mg, 0.80 mmol). After 6 min in a microwave reactor at 125 0C, the mixture was cooled to rt and concentrated. Purification by FCC gave the desired product (212.5 mg, 56percent).

The synthetic route of 4318-42-7 has been constantly updated, and we look forward to future research findings.

d) 1-(5-fftert-butyldimethylsilyloxy)methynpyridin-2-yl)piperidin-4-yl4- isopropyl-piperazine-1-carboxylate To a solution of 1-(5-((tert-butyldimethylsilyloxy)methyl)pyridin-2-yl)- piperidin-4-ol (257 mg, 1 mmol) in DCM (8 mL) was added BTC (297 mg, 1 mmol) and Et3N (152 mg, 1.5 mmol). The mixture was stirred at rt for 1 h before 1-isopropylpiperazine (128 mg, 1 mmol) was addedand the resulting mixture was stirred at rt overnight. The mixture was diluted with DCM (20 mL), washed with saturated K2C03?(20 mL) solution and brine (20 mL), dried andconcentrated to give the desired product as yellow oil (350 mg, 74percent). [LCMS: RtA?= 1.95min, m/z 477.2 [M+H]+].

4318-42-7, As the paragraph descriping shows that 4318-42-7 is playing an increasingly important role.
