In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 91717-22-5, name is 2-Amino-4-piperidino-6-methylpyrimidine, the common compound, a new synthetic route is introduced below. Recommanded Product: 91717-22-5
General procedure: Briefly, 4-methyl-6-(piperidin-1-yl)pyrimidin-2-amine 1 (0.30 mmol), benzaldehyde 2a (0.30 mmol), 10 equiv of dimethyl malonate 3a (3 mmol), and chiral catalyst Q4(10 mol%) were added to capped vials at 60C and stirred for 36 h. After completion of the reaction, as observed by TLC, the mixture was directly purified by column chromatography on silica gel (EtOAc/hexane=8:1), affording the product (R)-4a. However, the product (S)-4a was obtained using the Q5 catalyst. Enantiomeric excess of the product was determined by HPLC analysis using a Chiralpak IA column.
The synthetic route of 91717-22-5 has been constantly updated, and we look forward to future research findings.
