Analyzing the synthesis route of 16011-97-5

16011-97-5, The synthetic route of 16011-97-5 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.16011-97-5,N1,N4-Dimethylbutane-1,4-diamine,as a common compound, the synthetic route is as follows.

A mixture of 2-chloro-3-nitropyridin-4-amine (LXXXIII) (1.0 g, 5.76 mmol) and DIPEA (1.0 mL, 5.76 mmol) in THF (20 mL) was stirred at room temperature for 1 h. The reaction was concentrated to dryness and the residue was taken up in EtOAc and the organic layer was washed with 2 x water then 1 x brine solution. The organic layers were then separated and dried (MgSO4) before concentration to dryness to obtain N2-methyl-N2-(4- (methylamino)butyl)-3-nitropyridine-2,4-diamine (LXXXIV) (160 mg, 6.32 mmol, 109.6% yield) as dark brown gum which was used for next step without purification. ESIMS found for C11H19N5O2 m/z 254.1 (M+H).
