Ethyl 4-benzyloxy-1-methylindole-2-carboxylate → Ethyl 4-hydroxy-1-methyl-1H-indole-2-carboxylate

Participants

Reaction Steps

To 10% Pd/C (0.13 g) in EtOH (250 mL) was added ethyl 4-benzyloxy-1-methyl-1H-indole-2-carboxylate (1.33 g) and the suspension was shaken overnight under a hydrogen pressure of 3 atmospheres at room temperature. The residue left on evaporation of the filtered reaction mixture was chromatographed over silica gel with a mixture of EtOAc and hexane to give 0.43 g of the title compound. MS ES (M++H)=220.
