Procedure

5-(2-Aminoethyl)-N-{3-chloro-4-[3-(trifluoromethyl)phenoxy]phenyl}-5H-pyrrolo[3,2-d]pyrimidin-4-amine dihydrochloride (64.1 mg) and triethylamine (1.0 mL) were dissolved in dichloromethane (5.0 mL), 1-({[2-(methylsulfonyl)ethoxy]carbonyl}oxy)pyrrolidine-2,5-dione (45.6 mg) was added, and the mixture was stirred at room temperature for 2 hrs. Saturated aqueous sodium hydrogen carbonate was added to the reaction mixture under ice-cooling, and the mixture was extracted with ethyl acetate. The extract was dried over magnesium sulfate and concentrated, and the residue was separated and purified by silica gel column chromatography (eluent, ethyl acetate:methanol=100:0→ethyl acetate:methanol=95:5). Crystallization from diethyl ether/hexane gave the title compound (61.0 mg).
