Participants

Reaction Steps

After dissolving 1.5 ml of tetrahydrofuran in 22 mg of 5-[6-(4-benzyloxyphenyl)-7-(2-trimethylsilanylethoxymethyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yloxy]-indole-1-carboxylic ethylamide, a 1M solution of tetrabutylammonium fluoride in tetrahydrofuran was added and the mixture was refluxed for 2 hours. After returning it to room temperature, water was added and the precipitated crystals were filtered out and subjected to silica gel column chromatography (hexane-ethyl acetate) to obtain 2 mg of the title compound.
