After one hour of stirring, 1.36 g of ethyl 2-bromopropionate was added and the mixture was heated at reflux for 6 hours. The mixture was cooled, diluted with 25 ml of benzene, washed with water, 1 N aqueous sodium bicarbonate, and brine. It then was dried (MgSO4), the solvent was evaporated and the residue was chromatographed on silica gel, using a 1:1 v:v mixture of cyclohexane and ethyl acetate as eluent, to give 32, as a yellow oil.

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)+.

Any one of these steps may be slow and thus may serve as the rate determining step. In general, however, in the presence of the catalyst, the overall rate of the reaction is faster than it would be if the reactants were in the gas or liquid phase.Cinnolin-4(1H)-one, CAS: 18514-84-6, if you are interested, you can browse my other articles.

Solid-phase synthesis of substituted cinnolines by a Richter type cleavage protocol

Starting from triazene bound ortho-halo arenes on a solid support, palladium-catalyzed alkynylations and subsequent cleavage reactions under acidic conditions give rise to ortho-alkynylaryldiazonium salts, which in turn undergo cyclization to afford substituted 4-halo- and 4- hydroxycinnolines in moderate to good yields. The method is applicable to automated synthesis.

Alkylation of 4-hydroxycinnolines using ethyl bromoacetate resulted in N2-substituted acetic acids. These acids were converted to esters and amides. Some of the obtained acids were reduced with zinc dust to give 4-oxo-1,2,3,4-tetrahydro-2-cinnolineacetic acids. Several of the compounds were tested for their effect on central nervous system.
