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-hydroxy-methyl-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 (50 mL) and washed with water (2×20 mL). The organic phase was separated, dried, and concentrated. The residue was purified by flash silica column chromatography (hexane:ethyl acetate, 1:3 to pure ethyl acetate) to afford the title compound as a yellow solid (60 mg, 40%). ESI-MS m/z: 378 (M+H)+.
