4-[6-(4-Benzyloxyphenyl)-7-(2-trimethylsilanylethoxymethyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yloxy]-2-chlorophenylamine → 4-[4-(4-Amino-3-chlorophenoxy)-7-(2-trimethylsilanylethoxymethyl)-7H-pyrrolo[2,3-d]pyrimidin-6-yl]phenol

Participants

Reaction Steps

After dissolving 255 mg of the 4-[6-(4-benzyloxyphenyl)-7-(2-trimethylsilanylethoxymethyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yloxy]-2-chlorophenyl amine synthesized in Production Example 153-5 in 10 ml of ethanol and 3 ml of tetrahydrofuran, 100 mg of platinum oxide was added and the mixture was stirred overnight at room temperature under normal pressure in a hydrogen atmosphere. After filtering with celite, the filtrate was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography (hexane-ethyl acetate) to obtain 105 mg of the title compound.
