Reaction Steps

N-{3-[4-({3-Chloro-4-[3-(trifluoromethoxy)phenoxy]phenyl}amino)-5H-pyrrolo[3,2-d]pyrimidin-5-yl]propyl}-2-(methylsulfonyl)acetamide was obtained by the reaction in the same manner as in Example 155 (iv) using 5-(3-aminopropyl)-N-{3-chloro-4-[3-(trifluoromethoxy)phenoxy]phenyl}-5H-pyrrolo[3,2-d]pyrimidin-4-amine dihydrochloride (170 mg), 2-(methylsulfonyl)acetic acid (85.0 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (177 mg), 1-hydroxybenzotriazole monohydrate (141 mg), triethylamine (0.43 mL) and N,N-dimethylformamide (5.0 mL). To a solution of N-{3-[4-({3-chloro-4-[3-(trifluoromethoxy)phenoxy]phenyl}amino)-5H-pyrrolo[3,2-d]pyrimidin-5-yl]propyl}-2-(methylsulfonyl)acetamide in ethyl acetate (1.0 mL) was added 4N hydrochloric acid-ethyl acetate (0.50 mL) at room temperature, and the mixture was stirred at room temperature for 1 hr. After concentration under reduced pressure, diisopropyl ether was added, and the precipitated crystals were collected by filtration. The crystals were washed with diisopropyl ether to give the title compound (128 mg) as colorless powder crystals.
