To a mixture of 6.90 g 5-chloro-2-methyl-6-phenyl[1,2,4]triazolo[1,5-a]pyrimidine and 4.65 g 4-formylphenylboronic acid in 100 mL 1,2-dimethoxyethane were added 55 mL of a 10% w/w sodium carbonate solution and 1.03 g dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium (II). The resulting mixture was heated to 90° C. under an inert gas atmosphere for 18 h. The work up was performed by diluting the reaction mixture with water and dichloromethane, separating the phases and extraction of the aqueous phase with dichloromethane. The combined organic layers were dried over sodium sulphate and the solvent was evaporated. The residue was purified by chromatography on silica gel (dichloromethane/methanol) to yield the desired product.
