With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.21091-98-5,(4-Methylpiperazin-1-yl)(4-nitrophenyl)methanone,as a common compound, the synthetic route is as follows.
Step 2: (4-Amino-phenyl)-(4-methy -piperazine-l-yl)-methanoneTo a solution of (4-Methyl-piperazin-l-yl)-(4-nitro-phenyl)-methanone (14 g, 0.05623 mol) in MeOH (100 mL) was added Pd/C 10% (1.4 g) in portions and the Parr reaction vessel was purged with nitrogen for 10 min. reaction vessel was fixed in Pan- shaker at 60 psi pressure for 3 h. The reaction mixture was filtered through the Celite pad and the filtrate was concentrated under reduced pressure to afford the title compound [11 g, 89%]; LC-MS (ESI): Calculated mass 219.1; Observed mass: 220.1 [M+H]+ (RT: 0.16 min).
21091-98-5, 21091-98-5 (4-Methylpiperazin-1-yl)(4-nitrophenyl)methanone 716396, apiperazines compound, is more and more widely used in various fields.
