Procedure

Dissolve 2-[4-[2-(2,3,6,9-tetrahydro-1,3-dipropyl-2,6-dioxo-1H-purin-8-yl)propyl]phenoxy]acetic acid (800 mg, 1.87 mmol) in dimethylformamide (20 mL) and treat with N-hydroxysuccinimide (215 mg, 1.87 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (751 mg, 3.92 mmol). Stir for 1 hour and add to a stirring solution of ethylenediamine (20 mL of a 10% solution in methanol). Stir for 1 hour and dilute with chloroform (600 mL). Separate the organic phase, wash with 5% sodium carbonate (200 mL), then brine (300 mL). Dry (MgSO4) and evaporate the solvent in vacuo. Purify by radial chromatography (5→10% methanol/chloroform with 1% ammonium hydroxide) and recrystallize (10% isopropanol/hexane) to give the title compound (364 mg); mp 143-44° C.
