Reaction Steps

After dissolving 38 mg of 1-{4-[6-(4-benzyloxyphenyl)-7-(2-trimethylsilanylethoxymethyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yloxy]-2-chlorophenyl}-3-cyclopropylurea in 0.8 ml of tetrahydrofuran, 0.2 ml of tetrabutylammonium fluoride (1 M tetrahydrofuran solution) was added dropwise and the mixture was refluxed for 2 hours. It was then returned to room temperature, water was added, and liquid separation and extraction were performed with ethyl acetate and tetrahydrofuran. The organic layer was washed with water and saturated saline, concentrated and dried under reduced pressure to obtain 26 mg of the title compound.
