4,6-Dichloropyrimidine → 3-(6-Chloro-pyrimidin-4-ylamino)-4,N-dimethyl-benzamide

Participants

Reaction Steps

To a solution of 4,6-dichloropyrimidine (2.0 g, 13.4 mmol) in p-dioxane (50 mL), 3-amino-4,N-dimethyl-benzamide (3.0 g, 18.3 mmol) and DIEA (2.3 mL) were added. The resulting mixture was heated to reflux for 4 days. The solvent was removed in vacuo, the residue was taken in water and ethyl acetate, and the ethyl acetate layer was separated and concentrated. The product was purified by silica gel column chromatography using ethyl acetate:hexane (1:1) as eluent to afford the pale white solid product (1.6 g, yield 43%). MS (m/z): 277 (M+H).
