실험 절차

A mixture of 2.1 gm of 8-benzyl-3-[2-(4-nitrophenyl)ethyl]-1-propylxanthine (9), 1.02 gm of sodium carbonate, 3.82 ml of 1,2-dichloroethane and 0.59 ml of 2-(ethylamino)ethanol was heated in a steel pressure vessel under argon at 120 degrees C. for 3–5 hours*. The mixture was then cooled and vented to the atmosphere. The semisolid reaction mixture was triturated several times with 5–10 ml portions of methanol followed by methylene chloride and the combined solutions were evaporated to dryness. The residue was purified by column chromatography on silica gel using a gradient of 1:1 ethyl acetate-hexanes, ethyl acetate and 5% methanol in ethyl acetate. The appropriate fractions were collected and evaporated to dryness to yield a light orange solid of 8-benzyl-7-[2-ethyl(2-hydroxyethyl)amino]ethyl-3-[2-(4-nitrophenyl)ethyl]-1-propylxanthine.
