A solution of 5-(2-aminoethyl)-N-{3-methyl-4-[3-(trifluoromethoxy)phenoxy]phenyl}-5H-pyrrolo[3,2-d]pyrimidin-4-amine (174 mg), 2-(methylsulfonyl)acetic acid (54 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (112 mg), 1-hydroxybenzotriazole monohydrate (79 mg) and triethylamine (0.273 mL) in N,N-dimethylformamide (7.69 mL) was stirred at room temperature for 16 hrs. The reaction mixture was diluted with ethyl acetate (80 mL), and washed with water (60 mL). The organic layer was dried over magnesium sulfate and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography (eluent, ethyl acetate:methanol=100:0→92:8), and crystallized from diisopropyl ether to give the title compound (92 mg) as colorless crystals.
