Reaction Steps
4,6-Dichloropyrimidine (3.06 g, 20.5 mmol) was dissolved in dimethylformamide (“DMF”) (20 mL) and Cs2CO3 (10.0 g, 30.8 mmol) was added. Tetrahydro-2H-pyran-4-amine (1.87 g, 18.5 mmol) combined with DMF (5 mL) was added dropwise. A slight exotherm was observed. After agitating at ambient temperature for 2 hours, product peak was seen in LC/MS. Agitation continued overnight. The mixture was then diluted with ethyl acetate (250 mL) and washed 4 times with water, brine, dried and evaporated to give 6-chloro-N-(tetrahydro-2H-pyran-4-yl)pyrimidin-4-amine (2.86 g, 13.4 mmol, 65.2% yield) as a solid.
