반응 단계
To a mixture of 80 mg (0.54 mmol) (3-cyanophenyl)boronic acid, 150 mg (0.36 mmol) 1-[(6-chloro-3-pyridyl)methyl]-3-iodo-4-oxo-pyrido[1,2-a]pyrimidin-1-ium-2-olate (Synthesis described in WO 2009/099929), 1.6 mg (0.07 mmol) palladium acetate, 21 mg (0.07 mmol) tri-tert-butylphosphonium tetrafluoroborate and 295 mg caesium carbonate was added 50 ml of dioxane under argon. The mixture was heated to 80° C. for 48 hours. Silica was added and the product was obtained by column chromatographie (dichloromethane/methanol) (21 mg).
