A mixture of 6-chloro-2-iodo-9-isopropyl-9H-purine (a) (1.0 g, 3.1 mmol), tyramine (0.64 g, 4.65 mmol), triethylamine (0.63 g, 6.2 mmol) and 2-propanol (30 mL) was heated at 85° C. for 2 hr. The reaction mixture was concentrated and saturated aqueous sodium bicarbonate solution was added. The mixture was extracted with ethyl acetate (50 ml×3). The combined organic layers were dried over sodium sulfate, filtered, and concentrated. The residue was purified by column chromatography on silica gel (25 to 75% ethyl acetate in hexane eluant) to afford the title compound as a solid. MS m/z 424.1 (M+1).
