Procedure

Methyl 1-cyclopropyl-9-methyl-4-oxo-8-(pyridin-4-yl)-4H-quinolizine-3-carboxylate was prepared according to General Procedure A using methyl 8-chloro-1-cyclopropyl-9-methyl-4-oxo-4H-quinolizine-3-carboxylate (500 mg, 1.71 mmol) and pyridin-4-yl-boronic acid (253 mg, 2.05 mmol). Purification by flash silica column chromatography (CH2Cl2:MeOH) (1:0 to 9:1) afforded the title compound as a yellow solid (400 mg, 69%). ESI-MS m/z: 373 (M+K)+, 357 (M+Na)+, 335 (M+H)+.
