実験手順

A mixture of N-{3-chloro-4-[(3-fluorobenzyl)oxy]phenyl}-5-(3-chloropropyl)-5H-pyrrolo[3,2-d]pyrimidin-4-amine (839 mg), 3-chloro-4-[(3-fluorobenzyl)oxy]aniline (1.10 g) and 1-methyl-2-pyrrolidone (5 mL) was stirred at 140° C. for 1 hr. The reaction mixture was poured into water (10 mL) and adjusted to pH 8 with saturated aqueous sodium hydrogen carbonate. The mixture was extracted with ethyl acetate (40 mL×3), and the organic layers were combined and dried over anhydrous magnesium sulfate. After concentration under reduced pressure, the residue was subjected to silica gel-column chromatography (eluent, hexane:ethyl acetate=60:40→50:50) and further subjected to basic silica gel column chromatography (eluent, hexane:ethyl acetate=80:20→0:100). The object fraction was concentrated under reduced pressure. Chloroform-diisopropyl ether was added to the residue, and the solid was collected by filtration and dried. Recrystallization from ethyl acetate gave the title compound (74.5 mg).
