Procedure
A mixture of 3-(8-chloro-3-methylcinnolin-4-yl)phenol (0.21 g, 0.78 mmol), 4-bromomethylphenyl acetic acid methyl ester (0.42 g, 1.64 mmol), and cesium carbonate (1.70 g, 5.2 mmol) in acetone (15 mL) was refluxed for 2 hours. The reaction was quenched with water and extracted with ethyl acetate. The organic residue was purified by silica gel chromatography using 5-50% EtOAc/hexanes as eluent to provide the title compound (0.28 g) as a gum. MS (ESI) m/z 433; HRMS (ESI, [M+H]+) 433.1335.
