Versuchsvorschrift

A solution of 5-(4-chloro-5H-pyrrolo[3,2-d]pyrimidin-5-yl)pentyl acetate (200 mg) and 3-chloro-4-[3-(trifluoromethyl)phenoxy]aniline (265 mg) in isopropyl alcohol (3.5 mL) was stirred at 80° C. for 14 hrs. 1N Aqueous sodium hydroxide solution (2.1 mL) was added at 0° C., and the mixture was stirred at room temperature for 1 hr. 1N Hydrochloric acid (2.0 mL) was added to the reaction system, and the mixture was extracted with ethyl acetate. The organic layer was washed with aqueous sodium hydrogen carbonate and saturated brine and dried over magnesium sulfate. After concentration under reduced pressure, the residue was separated and purified by silica gel column chromatography (eluent, ethyl acetate→ethyl acetate:methanol=1:19) to give a colorless solid. Recrystallization from ethyl acetate-hexane gave the title compound (275 mg) as colorless crystals.
