Chemical engineers work across a number of sectors, processes differ within each of these areas, and are directly involved in the design, development, creation and manufacturing process of chemical products. 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)+., 18514-84-6
