Reaction Steps

To 5-chloropyrazolo[1,5-a]pyrimidine-3-carbaldehyde (50 mg, 0.276 mmol) in dioxane was added 4-(4-methylpiperazin-1-yl)aniline (264 mg, 1.381 mmol). The mixture was heated in microwave for 20 minutes at 120° C. The solid formed was isolated by filtration to yield 5-(4-(4-methylpiperazin-1-yl)phenylamino)pyrazolo[1,5-a]pyrimidine-3-carbaldehyde. The residue was used in the next step without further purification. LCMS (M+1=337).
