Reaction Steps

The procedure described in stage 2.4 is followed, starting with 0.157 g (0.54 mmol) of 5-bromo-2-(p-tolyl)pyrazolo[1,5-a]pyridine obtained in stage 8.3, 0.098 g (0.65 mmol) of 3-formylphenylboronic acid, 0.535 g (1.64 mmol) of caesium carbonate and 0.045 g (0.055 mmol) of [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) in 5 ml of a 9/1 mixture of tetrahydrofuran and water. After chromatography on silica gel, elution being carried out with a mixture of cyclohexane and ethyl acetate (8/2), 0.110 g (65%) of the expected product is obtained in the form of a beige powder.
