Procedure

After adding 2 ml of trifluoroacetic acid and 0.1 ml of thioanisole to 24 mg of 1-{4-[6-(4-benzyloxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yloxy]-2-chlorophenyl}-3-cyclopropylurea, the mixture was stirred at 45° C. for 30 minutes. The reaction system was concentrated under reduced pressure, saturated bicarbonate water was added to alkalinity, and then liquid separation and extraction were performed with ethyl acetate and tetrahydrofuran. The organic layer was washed with saturated saline, dried over anhydrous sodium sulfate, concentrated and dried under reduced pressure to obtain 15 mg of the title compound.
