Versuchsvorschrift

A mixture of 4-chloro-6-(2-furyl)-5-methyl-5H-pyrrolo[3,2-d]pyrimidine (92 mg), 3-methyl-4-[(6-methylpyridin-3-yl)oxy]aniline (102 mg) and 1-methyl-2-pyrrolidinone (2.5 mL) was stirred at 140° C. for 3.5 hrs, poured into water (10 mL) and adjusted to pH 8 with saturated aqueous sodium hydrogen carbonate. The mixture was extracted with ethyl acetate (25 mL×2), 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=1:1→0:1). The object fraction was concentrated under reduced pressure. Diethyl ether was added to the residue, and the solid was collected by filtration and dried under reduced pressure at 60° C. to give the title compound (105 mg).
