{2-[(2-aminoethyl)amino]-4-(2,4-dichlorophenyl)pyrimidin-5-yl}methan-1-ol was dissolved in 3 mL of anhydrous THF and 1.47 g (4.50 mmol) of anhydrous cesium carbonate was added. 2-chloro-5-nitro-6-aminopyridine (143 mg, 0.9 mmol) was added in one portion and the yellow suspension heated at 70° C. for 18 h. The reaction mixture was filtered, concentrated and the residue chromatographed (silica gel, 5% methanol/methylene chloride) to give [4-(2,4-dichlorophenyl)-2-({2-[(5-nitro(2-pyridyl))amino]ethyl}amino)pyrimidin-5-yl]methan-1-ol, 216 mg (53%), as a yellow solid.
