To 5-chloropyrazolo[1,5-a]pyrimidine-3-carbaldehyde (40 mg, 0.221 mmol) in dioxane was added 3-(4-methylpiperazin-1-yl)aniline (127 mg, 0.663 mmol). The mixture was heated in microwave at 120° C. Dichloromethane and water were added, and the product extracted in dichloromethane. The organic layer was then dried over Na2SO4 and concentrated under reduced pressure to yield 5-(3-(4-methylpiperazin-1-yl)phenylamino)pyrazolo[1,5-a]pyrimidine-3-carbaldehyde. LCMS (M+1=337)
