After adding 200 ml of phosphorus oxychloride to 20 g of the 6-(4-benzyloxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-ol synthesized in Production Example 153-2, the mixture was stirred at 140° C. for 3 hours and the reaction system was concentrated at room temperature. Ice water was added to the residue, and liquid separation and extraction were performed with an ethyl acetate:tetrahydrofuran (5:1) mixed solvent. The organic layer was washed with water and saturated saline, dried over sodium sulfate and concentrated to dryness to obtain 12 g of the title compound.
