Reaction Steps
A mixture of 8-chloro-1-cyclopropyl-9-methyl-4-oxo-4H-quinolizine-3-carboxylic acid ethyl ester (120 mg, 0.400 mmol), 4-methoxy-phenyl boronic acid (73 mg, 0.48 mmol), (Ph3P)2PdCl2 (28 mg, 0.040 mmol), and Na2CO3 (190 mg in 0.8 mL of water, 1.80 mmol) in THF (5 mL) was degassed 3 times under N2 and heated to 80° C. overnight. The reaction mixture was diluted with ethyl acetate, and washed with water. The organic phase was separated, dried, and concentrated. The residue was purified by flash silica column chromatography (hexane:ethyl acetate, 1:2) to afford the title compound as a yellow solid (68 mg, 45%). ESI-MS m/z: 378 (M+H)+.
