Versuchsvorschrift

A mixture of 3-bromo-2-(4-fluoro-phenyl)-4-hydroxy-1-phenyl-1H-pyrrolo[2,3-c]pyridine-5-carboxylic acid ethyl ester (200 mg), Zn(CN)2 (31 mg), Zn dust (3.5 mg), Pd2(dba)3 (20 mg), dppf (24.4 mg) in DMA (1 mL) was heated to 120° C. for 145 min; then the mixture was partitioned between EtOAc and water, the organic phase was then washed with sat. NaCl solution, dried over anhydrous sodium sulfate, filtered and concentrated sequentially to give a residue, which was purified with column to give desired title compound (83 mg). The title compound, ESI MS (m/z): 402 (M+H)+.
