Reaction Steps

To a mixture of 2,4-dichloropyrimidine-5-carbonitrile (1.0 equiv. 61.4) and (4-ethylpyrimidin-5-yl)methanamine (1.0 equiv.) in isopropanol (0.2 M) was added DIEA (2.0 equiv.). The mixture was stirred at room temperature under nitrogen overnight. The reaction mixture was extracted with ethyl acetate, the organic layer was washed with a solution of ammonium chloride and concentrated under vacuum to give crude product, which was purified by silica gel chromatography (30% ethyl acetate in petroleum ether) to afford the title compound (11.4% yield) as brown solid. 1H-NMR (400 MHz, CD3OD) δ (ppm) 9.95 (d, J=3.2 Hz, 1H), 8.64 (d, J=12.0 Hz, 1H), 8.58 (d, J=19.6 Hz, 1H), 4.70 (d, J=20.4 Hz, 2H), 2.97-2.87 (m, 2H), 1.33-1.27 (m, 3H); MS (ESI) m/z 275.1 [M+H]+.
