Introduce a common compound, CAS is 18514-84-6, Name is Cinnolin-4(1H)-one, belongs to cinnoline compound. 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).

Introduce a common compound, CAS is 18514-84-6, Name is Cinnolin-4(1H)-one, belongs to cinnoline compound. 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)+.
