With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.70261-81-3,1-Methyl-4-(4-nitrobenzyl)piperazine,as a common compound, the synthetic route is as follows.,70261-81-3
A mixture of 1-methyl-4-(4-nitro-benzyl)-piperazine (3.09 g, 13.1 mmol), zinc dust (4.29 g, 65.6 mmol) and ammonium chloride (2.81 g, 52.5 mmol) in methanol (100 mL) was refluxed 1h, cooled, filtered through Celite (washing with methanol) and evaporated to provide 4-(4-methyl-piperazin-1-ylmethyl)-phenylamine (2.67 g, 99% yield) as a pale yellow, waxy solid. 1H-NMR (DMSO-d6, 500 MHz) 6.89 (d, 2H), 6.49 (d, 2H), 4.89 (s, 2H), 3.24 (s, 2H), 2.3 (br m, 8H) ppm; MS (FIA) 206.2 (M+H); HPLC (Method A) co-elutes with solvent front.
The synthetic route of 70261-81-3 has been constantly updated, and we look forward to future research findings.
