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. 18368-73-5, name is 3-Methyl-2-nitropyridine, the common compound, a new synthetic route is introduced below. Recommanded Product: 18368-73-5
General procedure: To a stirred mixture of 1.00 mmol of nitropicoline 35 or 63, 1.20 mmol of the appropriate benzaldehyde, and 1.5 mmol of Huenig’s base in THF (7 mL/g of nitropicoline 35/63) was added 1.3 mmol of a 1 M THF solution of TBAF. The resulting mixture was heated 60 C for 1.5e2.0 h in the case of 2,3-dihydrofuro[3,2-c] pyridines or for 18 h in the case of 2,3-dihydrofuro[2,3-b]pyridines. After cooling to room temperature, the reactions were quenched with sat. aqueous NH4Cl. The solution was extracted with EtOAc, dried over MgSO4, and concentrated under reduced pressure. The residue was purified by silica gel chromatography as specified above.
The synthetic route of 18368-73-5 has been constantly updated, and we look forward to future research findings.
