실험 절차

To 5-chloropyrazolo[1,5-a]pyrimidine-3-carbaldehyde (40 mg, 0.221 mmol) in dioxane was added 3-((1H-imidazol-1-yl)methyl)aniline (115 mg, 0.663 mmol). The mixture was heated in microwave for 120 minutes at 120° C. EtOAc was added to the mixture, and washed with water. The organic layer was then dried over Na2SO4 and solvent was removed under reduced pressure to yield 5-(3-((1H-imidazol-1-yl)methyl)phenylamino)pyrazolo[1,5-a]pyrimidine-3-carbaldehyde. The resulting solid was used in the next step without further purification. LCMS (M+1=319)
