18514-84-6,Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.4,5-Dimethyl-1,3-dioxol-2-one,introducing its new discovery.

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).

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 21905-86-2, help many people in the next few years.18514-84-6

To a solution of cinnolin-4(lH)-one in DMF (0.1 M) was added K2CO3 (1.2 eq) and methyl 5-(bromomethyl)-2-fluorobenzoate (prepared as described in US 2007/0021427 Al, 1 eq). The mixture was stirred and heated tolOO 0C for Ih. After cooling to RT the solvent was removed under reduced pressure and the residue was partitioned between DCM and H2O. The organic phase was washed with brine, dried (Na2SO4) and filtered and the solvent was removed under reduced pressure. The product was isolated by flash chromatography on silicagel, using a gradient of DCM/MeOH (from 0% to 10% MeOH in 10 CV). The 2-[4-fiuoro-3- (methoxycarbonyl)benzyl]cinnolin-2-ium-4-olate was eluted after the title compound.MS (ES) Ci8Hi3FN2O3 requires: 312, found: 313 (M+H)+.
