Procedure

To a solution of 4,6-dichloro-pyrimidine (1 g, 6.7 mmol) and DIPEA (1.03 g, 8 mmol) in iPrOH (20 mL) was added N,N-dimethyl-propane-1,3-diamine (714 g, 7 mmol) at room temperature. The resulting mixture was stirred for 2 hours. Water was added and the mixture was extracted with DCM. The combined extracts were washed with brine, dried over anhydrous Na2SO4, and concentrated to give the crude product, which was purified by flash chromatography on silica to obtain the title compound (1.15 g, yield: 80%). MS (ESI): 215 [M+H]+.
