Participants

Reaction Steps

To a mixture of 3-bromo-2-(4-chloro-phenyl)-4-hydroxy-1-phenyl-1H-pyrrolo[2,3-c]pyridine-5-carboxylic acid ethyl ester (200 mg, 0.42 mmol)(from Example 36(d)) in ethanol (12 mL) and DMF (3 mL) was added Pd/C (10% wet, containing 50% water)(120 mg) was stirred under hydrogen atmosphere (balloon pressure) for 30 h. Reaction mixture was filtered through a pad of celite and rinsed with EtOAc. Filtrate was concentrated and purified by silica gel chromatography (eluting with 25%-50% EtOAc/hexanes) to give the title compound 42 mg. MS-(+)-ion: M+1=359.04.
