Procedure

A mixture of 4-{2-[(2-aminoethyl)amino]-5-imidazolylpyrimidin-4-yl}benzene-carbonitrile (30 mg, 0.098 mmol), 3-nitrobenzoic acid (17 mg, 0.1 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC) (19 mg, 0.1 mmol), 1-bydroxybenzotriazole hydrate (HOBT) (14 mg, 0.1 mmol), and 4-dimethylaminopyridine (DMAP) (12 mg, 0.1 mmol) in DMA (500 uL) were stirred at room temperature. After 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 resulting product, N-(2-{[4-(4-cyanophenyl)-5-imidazolylpyrimidin-2-yl]amino}ethyl)(3-nitrophenyl)carboxamide weighing 32 mg (70% yield) was approximately 95% pure by LCMS and HPLC.
