Extracurricular laboratory: Synthetic route of 3939-13-7

The synthetic route of 3939-13-7 has been constantly updated, and we look forward to future research findings.

Adding a certain compound to certain chemical reactions, such as: 3939-13-7, 2-Fluoronicotinonitrile, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Computed Properties of C6H3FN2, blongs to pyridine-derivatives compound. Computed Properties of C6H3FN2

Synthesis of intermediate VX001: Isoxazolo[5,4-b]pyridin-3-amine 909 mg (8.1 mmol) of KO-t-Bu were added, with vigorous stirring, to a suspension of 668 mg (8.9 mmol) of acethydroxamic acid in DMF (20 ml), and the mixture was stirred for 30 min at RT. 990 mg (8.1 mmol) of 2-fluoro-nicotinonitrile were then added, and stirring was carried out for a further 5 h at 50 C. The mixture was then extracted with EA and the organic phase was dried over Na2SO4, filtered and concentrated in vacuo. CC (hexane/EA 7:3) of the residue yielded 305 mg (2.3 mmol, 28%) of isoxazolo[5,4-b]pyridin-3-amine.

The synthetic route of 3939-13-7 has been constantly updated, and we look forward to future research findings.
