Procedure

To a solution of ethyl (4-chloro-5H-pyrrolo[3,2-d]pyrimidin-5-yl)acetate (140 mg) in isopropyl alcohol (0.6 mL) was added 3-methyl-4-[(6-methylpyridin-3-yl)oxy]aniline (188 mg), and the mixture was stirred in an oil bath at a temperature of 110° C. for 2 hrs. The reaction mixture was allowed to cool to room temperature, diluted with 5% aqueous sodium hydrogen carbonate solution (20 mL) and extracted with ethyl acetate (25 mL×3). The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the obtained residue was subjected to silica gel column chromatography (basic silica gel, eluent:ethyl acetate/methanol=10/0→9/1). The object fraction was concentrated under reduced pressure. Diisopropyl ether was added to the residue, and the resultant precipitate was collected by filtration and dried under reduced pressure to give the title compound (210 mg) as white powder crystals.
