Reaction Steps
To 5-chloropyrazolo[1,5-a]pyrimidine-3-carbaldehyde (50 mg, 0.276 mmol) in dioxane was added 3-((diethylamino)methyl)aniline (148 mg, 0.829 mmol). The mixture was heated in microwave for 140 minutes at 120° C. Dichloromethane was added, and washed with water. The organic layer was dried over Na2SO4 and concentrated under reduced pressure. The resulting solution was prepared by TLC (10% MeOH/DCM) to yield 10 mg 5-(3-((diethylamino)methyl)phenylamino)pyrazolo[1,5-a]pyrimidine-3-carbaldehyde (11% yield). LCMS (M+1=324)
