Procedure

2-(2-{2-[4-({3-Chloro-4-[3-(trifluoromethyl)phenoxy]phenyl}amino)-5H-pyrrolo[3,2-d]pyrimidin-5-yl]ethoxy}ethyl)-1H-isoindole-1,3(2H)-dione (200 mg) was dissolved in ethanol (5.0 mL), hydrazine monohydrate (3.0 mL) was added, and the mixture was stirred for 1 hr. To the reaction mixture was added saturated aqueous sodium hydrogen carbonate 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 basic silica gel column chromatography (eluent, ethyl acetate:methanol=100:0→ethyl acetate:methanol=95:5). The title compound (146.0 mg) was obtained as colorless crystals by the reaction in the same manner as in Example 180 using the obtained oil, acetic anhydride (1.0 mL), N-methylmorpholine (1.0 mL) and tetrahydrofuran (5.0 mL).
