N-{2-[4-({3-Chloro-4-[3-(trifluoromethyl)phenoxy]phenyl}amino)-5H-pyrrolo[3,2-d]pyrimidin-5-yl]ethyl}-3-hydroxypropanamide was obtained by the reaction in the same manner as in Example 202 (iii) using 5-(2-aminoethyl)-N-{3-chloro-4-[3-(trifluoromethyl)phenoxy]phenyl}-5H-pyrrolo[3,2-d]pyrimidin-4-amine dihydrochloride (300 mg), 3.6 M aqueous solution (0.25 mL) of 3-hydroxypropanoic acid, 1-hydroxybenzotriazole monohydrate (231 mg), N-[3-(dimethylamino)propyl]-N-ethylcarbodiimide hydrochloride (330 mg), triethylamine (0.8 mL) and N,N-dimethylformamide (3 mL). The obtained N-{2-[4-({3-chloro-4-[3-(trifluoromethyl)phenoxy]phenyl}amino)-5H-pyrrolo[3,2-d]pyrimidin-5-yl]ethyl}-3-hydroxypropanamide was dissolved in ethyl acetate (2 mL), and 4N hydrochloric acid-ethyl acetate (0.1 mL) was added. The obtained product was recrystallized from ethyl acetate to give the title compound (63.1 mg) as a white powder.
