Commercially available N-methyl-1-(4-pyridinyl)methanamine (0.305 g, 2.5 mmol) was dissolved in THF (5 mL). To this solution was added triethylamine (0.38 mL, 2.73 mmol), followed by 2,4,6-trichloro-5-fluoropyrimidine (0.5 g, 2.5 mmol), which was dissolved in THF (5 mL). The reaction was left to stir for 2.5 hours. The reaction mixture was diluted with water, then extracted with ether. The organics were dried (MgSO4) and concentrated. The resulting material was purified via filtration over silica gel with a solvent mixture of 5% MeOH in 95% DCM as the mobile phase to provide 2,6-dichloro-5-fluoro-N-methyl-N-(4-pyridinylmethyl)-4-pyrimidinamine as a brown oily solid (0.3516 g, 49%). LCMS: (M+H)+=287.0.
