55121-99-8 (4-Aminophenyl)(4-methylpiperazin-1-yl)methanone 231408, 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.55121-99-8,(4-Aminophenyl)(4-methylpiperazin-1-yl)methanone,as a common compound, the synthetic route is as follows.
55121-99-8, General Procedure for Synthesis of Examples 8 – 42; EPO EPO EPO The starting pyrimidyl chloride (54 mg, 0.15 mmol) was placed in a 2-5 mL microwave reaction vessel from Personal Chemistry, suspended in iPrOH (2 mL), and treated with concentrated HCI (0.075 mL) and an aniline monomer (0.3 mmol). The vial was sealed and the reaction was heated in the Smith Synthesizer at 170 0C for 20 minutes. The cap was removed and Et3N (0.5 mL) and CH2CI2 (2 mL) were added. The solvent was evaporated and the residue purified by reverse phase mass directed prep HPLC [conditions: 4 x 20 mm Phenomenex Luna C18(2) 3 micron column, eluted with 10-100% Methanol (0.075% Formic Acid) / Water (0.1% Formic Acid), 3 minute gradient time, 4 minute run, 2 ml/minute]. The appropriate fractions were combined and concentrated to give the final products. Compounds with greater than 80% purity by peak area were submitted for screening and are shown in the table below.
