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 (634 mg), 2-methylaminoethanol (534 mg) and N,N-dimethylformamide (5 mL) was stirred at room temperature for 64 hrs. After concentration under reduced pressure, saturated aqueous sodium hydrogen carbonate (10 mL) was added to the residue, and the mixture was extracted with ethyl acetate (55 mL×2). The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by basic silica gel column chromatography (eluent, hexane:ethyl acetate=80:20→0:100). 4N Hydrogen chloride-ethyl acetate solution (10 mL) was added to the obtained amorphous solid and, after concentration under reduced pressure, the residue was recrystallized from ethanol-ethyl acetate to give the title compound (523 mg).
