A 2.64 g portion of 4-[[4-(3-pyridinyl)-2-pyrimidinyl]amino]phenol was dissolved in 60 ml of dimethylformamide by warming on a steam bath and then cooled. A 2.0 g portion of diisopropylaminoethyl chloride hydrochloride was added and dissolved with stirring. A 20 ml portion of 5N sodium hydroxide was added dropwise over 5 minutes, then 5 ml of water was added and the mixture was stirred for 20 hours. The mixture was then heated on a steam bath for 30 minutes, allowed to stand 48 hours and then evaporated. The residual gum was purified by flash dry column chromatography on silica gel eluting fractions 1-3 with methanol and fractions 4-6 with 1% methanol in chloroform. Fractions 4-6 were combined and evaporated, giving 500 mg of the desired product.
