Reaction Steps

0.20 g (1.09 mmol) of 5-bromo-2-cyanopyrimidine (ABCR 245244), 0.325 g (1.52 mmol) of 6-ethyl-3,4-dihydro-2H-chromen-4-aminium chloride and 0.35 g (3.3 mmol) of triethylamine in 1.5 ml of N,N-dimethylacetamide are heated in a closed cuvette in the microwave at 200° C. for 120 minutes (Biotage Initiator, http://www.biotage.com/DynPage.aspx?id=22001). The crude mixture obtained in this manner is applied to silica gel and purified by column chromatography using the mobile phase heptane/ethyl acetate. Concentration gives 0.03 g of 5-[(6-ethyl-3,4-dihydro-2H-chromen-4-yl)amino]pyrimidine-2-carbonitrile (wax-like) (yield 8% at a purity of 80%).
