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. 108130-10-5, name is Ethyl 2,6-dichloro-4-methylnicotinate, the common compound, a new synthetic route is introduced below. Product Details of 108130-10-5
a) Synthesis of 6-chloro-2-(ethyl(methyl)amino)-4-methyl-pyridine-3-carboxylic acid ethylester A mixture of 8.2 g (35.0 mmol) 2,6-dichloro-4-methyl-pyridine-3-carboxylic acid ethylester, 3.7 ml (43.8 mmol) N-methylethylamine and 8.9 ml (52.5 mmol) DIPEA in NMP (25 ml) was heated in the MW to 90 C. for 1 h. Then the solution was diluted with water, a 1M aq. NaOH sol. and EtOAc. The organic layer was separated, dried over MgSO4 and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 9:1) provided 4.0 g (15.6 mmol, 44%) 6-chloro-2-(ethyl(methyl)amino)-4-methyl-pyridine-3-carboxylic acid ethylester.
The synthetic route of 108130-10-5 has been constantly updated, and we look forward to future research findings.
