Procedure

To a solution of ethyl 5-[(4-chloro-5H-pyrrolo[3,2-d]pyrimidin-5-yl)methyl]-2-furoate (200 mg) in 1-methyl-2-pyrrolidone (1.3 mL) was added 3-chloro-4-[(3-fluorobenzyl)oxy]aniline (247 mg), and the mixture was heated to 140° C. and stirred 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 (20 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 (silica gel, eluent:ethyl acetate/methanol=10/0→8/2). The object fraction was concentrated under reduced pressure and dried to give the title compound (307 mg) as a pale-yellow solid.
