Downstream synthetic route of 32601-86-8

32601-86-8 2-Chloro-3-methylquinoxaline 236276, aquinoxaline compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.32601-86-8,2-Chloro-3-methylquinoxaline,as a common compound, the synthetic route is as follows.

Preparation 19: 2-methyl-3-F4- (PHenVLmethVL) piperazin-1-ylLQUINOXALINE 2-Chloro-3-methylquinoxaline (1.0 g, 5.6 MMOL) and N-benzylpiperazine (2.9 ML, 16.8 MMOL) were mixed and heated to 125 C for 18 h. Saturated aqueous sodium hydrogen carbonate was added and the product was extracted with chloroform. The combined organic extracts were dried (NA2SO4) and concentrated in vacuo to give a dark red oil. The crude product was purified by flash chromatography using silica gel eluting with methanol : dichloromethane (15: 85) to give the pure product as a red oil which solidified upon standing (1.63 g, 94%)., 32601-86-8
