Procedure

5-(2-Aminoethyl)-N-{3-chloro-4-[3-(trifluoromethyl)phenoxy]phenyl}-5H-pyrrolo[3,2-d]pyrimidin-4-amine dihydrochloride (54.1 mg) and triethylamine (0.7 mL) were dissolved in dichloromethane (10 mL), 1,1′-carbonylbis(1H-imidazole) was added, and the mixture was stirred at room temperature. After 1 hr, 2-(methylsulfonyl)ethanamine (1.0 mL) was added, and the mixture was further stirred for 1 hr. Saturated aqueous sodium hydrogen carbonate was added to the reaction mixture under ice-cooling, and the mixture was extracted with dichloromethane. 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=90:10). crystallized from diethyl ether/ethyl acetate/hexane to give the title compound (37.6 mg).
