Sep 2021 News Brief introduction of 4-Methyl-1-piperazineacetic acid

The synthetic route of 54699-92-2 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.54699-92-2,4-Methyl-1-piperazineacetic acid,as a common compound, the synthetic route is as follows.,54699-92-2

Example 11; Synthesis of Active Esters Of N-Methyl Piperazine Acetic Acid Via Oxalyl Chloride (Scheme B, FIG. 4B); To a suspension of N-methyl piperazine acetic acid (N-MPAA) (79 mg, 0.5 mmol) in DCM (25 mL) was added a solution of oxalyl chloride (4 mL, 0.8 mmol, 2.0 M solution in DCM) over 10 minute at room temperature. After another 30 minutes of reaction, solvent and excess reagent were removed under reduced pressure to give a white solid (23). A solution of NHS (57 mg, 0.5 mmol) in DCM (25 mL) was added to the solid followed by ss-TBD (390 mg, 1 mmol, 2.6 mmol/g). The resulting solution was sonicated for 5 minute when all solid dissolved. The ss-TBD resin was removed by filtration and solvent was evaporated to yield a white foam (97% yield). Product was characterized by ES-MS as before.

The synthetic route of 54699-92-2 has been constantly updated, and we look forward to future research findings.
