Reaction Steps

A solution of 4-chloro-6-methoxy-N,N-dimethylpyrimidin-2-amine (0.350 g, 2.19 mmol, 1 eq) in 10 ml anhydrous DMF was degassed with Ar for 5 min. Zn(CN)2 (0.155 g, 1.32 mmol, 0.6 eq) and Pd(PPh3)4 (0.253 g, 0.219 mmol, 10 mol %) were added and the mixture was heated to 95° C. After 23 h the reaction was cooled to room temperature and the mixture was diluted with Et2O and NH4OH (28%). After stirring for 1 h the layers were separated. The organic layer was washed with water (×3), brine (×1), and dried over Na2SO4. The inorganics were filtered off, and the solvent was removed in vacuo. Purification via flash chromatography yielded 0.214 g (1.43 mmol, 65% yield) of 2-amino-6-methoxypyrimidine-4-carbonitrile.
