Procedure

A mixture of 2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-vinyl]-1H-pyrrolo[2,3-b]pyridin-5-carboxylic acid (680 mg, 1.24 mmol) and 10% palladium on activated carbon (204 mg) in methanol (300 mL) was heated at 50° C. under 50 bar of hydrogen in a steel bomb and kept for 5 h. The mixture was cooled to 25° C., the solids were filtered off, washed with ethyl acetate and the filtrate concentrated in vacuo to afford 2-[2-cyclopentyl-1-(4-methanesulfonyl-phenyl)-ethyl]-1H-pyrrolo[2,3-b]pyridin-5-carboxylic acid (600 mg, 87%) which was used without further purification.
