A mixture of 1-benzyl-3,7-dichloro-4-hydroxy-1H-pyrrolo[2,3-c]pyridine-5-carboxylic acid ethyl ester (155 mg), Zn(CN)2 (30 mg), Zn dust (3.3 mg), Pd2(dba)3 (19.4 mg), dppf (23.5 mg) in DMA (1.5 mL) was heated to 120° C. for 90 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 (100 mg). 1H NMR (200 MHz, CDCl3): δ(ppm)=12.16 (s, 1H), 7.4-7.1 (m, 6H), 5.71 (s, 2H), 4.53 (q, 2H, J=7.1 Hz), 1.49 (t, 3H, J=7.1 Hz).
