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.
