With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.6639-87-8,6-Nitroquinoxaline,as a common compound, the synthetic route is as follows.
6639-87-8, [0170] To a solution of 6-nitroquinoxaline (2.2 g, 12.57 mmol, 1.0 eq) in MeOH, was added dropwise Ranney-Ni (0.7 mL) and hydrazine hydrate (5 mL) was added at 0 C. The mixture was stirred for 2 h at RT. The mixture was filtered and washed with MeOH. The solid was dried under vacuo to give the product (1.8 g, yield: 98.75%>). LC/MS: m/z (M++l) = 146. 42C. Preparation of N-methylquinoxalin-6-amine
As the paragraph descriping shows that 6639-87-8 is playing an increasingly important role.
