Procedure

According to Scheme 13: A mixture of 3-[5-acetyl-1-((1R,2R)-4-bromo-6-fluoro-2-hydroxy-indan-1-yl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridin-3-yl]-benzonitrile (11d) (0.05 g, 0.10 mmol), tetramethyltin (101 mg, 0.566 mmol) and tetrakis(triphenylphosphine)palladium(0) (6 mg, 0.005 mmol) in N,N-dimethylformamide (2 ml) was stirred at 110° C. for 18 h. The mixture was purified by reverse phase HPLC (CH3CN/water gradient with 0.1% trifluoroacetic acid) to give 23 mg of 3-[5-acetyl-1-((1R,2R)-6-fluoro-2-hydroxy-4-methyl-indan-1-yl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridin-3-yl]-benzonitrile (19a).
