ethyl 1-(2-benzyloxyethyl)-2-(2,4-bismethoxymethoxyphenyl)-3-cyclohexyl-1H-pyrrolo[2,3-b]pyridine-6-carboxylate → ethyl 2-(2,4-bismethoxymethoxyphenyl)-3-cyclohexyl-1-(2-hydroxyethyl)-1H-pyrrolo[2,3-b]pyridine-6-carboxylate

Participants

Reaction Steps

To a solution of ethyl 1-(2-benzyloxyethyl)-2-(2,4-bismethoxymethoxyphenyl)-3-cyclohexyl-1H-pyrrolo[2,3-b]pyridine-6-carboxylate (727 mg, 1.20 mmol) in tetrahydrofuran (10 ml) and methanol (10 ml) was added 7.5% palladium carbon (225 mg), and the mixture was stirred at atmospheric pressure and in a hydrogen atmosphere at room temperature for 12 hr. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure to give ethyl 2-(2,4-bismethoxymethoxyphenyl)-3-cyclohexyl-1-(2-hydroxyethyl)-1H-pyrrolo[2,3-b]pyridine-6-carboxylate as a crude product. The obtained compound was used in Step 7 without further purification.
