Research on new synthetic routes about Cinnolin-4(1H)-one

This molecular description is the mechanism of the reaction; it describes how individual atoms, ions, or molecules interact to form particular products.If you are interested, you can also browse other articles of Cinnolin-4(1H)-one, , We look forward to the emergence of more reaction modes in the future.

One of the major reasons is to use measurements of the macroscopic properties of a system, the rate of change in the concentration of reactants or products with time, to discover the sequence of events that occur at the molecular level. 18514-84-6, introduce a new downstream synthesis route., 18514-84-6

Intermediate 2: Preparation of 3-Bromo-l,4-dihydro-4-cinnolinone:Bromine (0.8 ml) in acetic acid (10 ml) was added to a mixture of cinnolin-4- one (1.5 g, 10.27 mmol), sodium acetate (1.51 g, 18.49 mmol) and acetic acid (15 ml) maintained at 100 0C and stirred at that temperature for Ih. The mixture was concentrated under reduced pressure to half the initial volume and poured into water. The precipitated solid was filtered, washed with water and dried under reduced pressure. Yield: 64%. 1H-NMR (delta ppm, CDCl3, 300 MHz): 13.87 (br. s, IH); 8.06 (d, J = 7.8, IH); 7.84-7.80 (m, IH); 7.61 (d, J = 8.7, IH); 7.49 (t, J = 7.8, IH).
