Procedure

After dissolving 30 mg of 5-[6-(4-benzyloxyphenyl)-7-(2-trimethylsilanylethoxymethyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yloxy]indole-1-carboxylic ethylamide in 1 ml of trifluoroacetic acid and 0.1 ml of thioanisole, the mixture was stirred at 50-55° C. The mixture was then returned to room temperature, saturated sodium bicarnobate water was added to alkalinity, and liquid separation and extraction were performed with an ethyl acetate-tetrahydrofuran (5:1) mixed solvent. The organic layer was concentrated, 1 ml of tetrahydrofuran and 1 ml of 2N aqueous sodium hydroxide were added to the residue, and the mixture was stirred at room temperature for 5 minutes. After neutralization with 1N hydrochloric acid, liquid separation and extraction were performed with an ethyl acetate-tetrahydrofuran (5:1) mixed solvent. The organic layer was concentrated and the residue was subjected to silica gel column chromatography (hexane-ethyl acetate) to obtain 5 mg of the title compound.
