Procedure

To a suspension of 5-(2-aminoethyl)-N-{3-chloro-4-[3-(trifluoromethyl)phenoxy]phenyl}-5H-pyrrolo[3,2-d]pyrimidin-4-amine dihydrochloride (150 mg) and triethylamine (0.40 mL) in tetrahydrofuran (5.0 mL) was added 1-chlorocarbonyl-1-methylethyl acetate (0.12 mL) at room temperature. After stirring at room temperature for 3 days, aqueous sodium hydrogen carbonate was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate and concentrated under reduced pressure. To a solution of the residue in ethanol (3.0 mL) was added 1N aqueous sodium hydroxide solution (1.5 mL) at room temperature. After stirring at room temperature for 24 hrs, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate and concentrated under reduced pressure, and the residue was separated and purified by basic silica gel column chromatography (eluent, ethyl acetate→ethyl acetate:methanol=9:1) to give the title compound (133 mg) as colorless crystals.
