Reaktionsschritte

A mixture of 4-{2-[(2-aminoethyl)amino]-5-imidazolylpyrimidin-4-yl}benzenecarbonitrile (30 mg, 0.098 mmol), 2-chloro-5-(trifluoromethyl)pyridine (18 mg, 0.098 mmol), and Hünig's base (70 uL, 0.4 mmol) in DMA (500 uL) were heated to 80° C. After stirring for 12 hours, the reaction was diluted with ethyl acetate (10 ml) and extracted with sat. aq. NaHCO3 (2×5 ml), water (3×5 ml), brine (5 ml), dried with Na2SO4, filtered, and concentrated. The product was purified by preparative HPLC using a reverse phase column and a water/acetonitrile gradient. The product 4-{5-imidazolyl-2-[(2-{[5-(trifluoromethyl)(2-pyridyl)]amino}ethyl)amino]pyrimidin-4-yl}benzenecarbonitrile was obtained as a off-white solid in 5% yield.
