Reaction Steps

According to Scheme 14: A mixture of cyclopropylboronic acid (28 mg, 0.33 mmol), 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), K2CO3 (83 mg, 0.606 mmol) and tetrakis(triphenylphosphine)palladium(0) (17 mg, 0.005, 0.015 mmol) in CH3CN (2 ml) and water (0.75 ml) was stirred at 110° C. for 2 h under microwave irradiation. The mixture was purified by reverse phase HPLC (CH3CN/water gradient with 0.1% trifluoroacetic acid) to give 9 mg of 3-[5-acetyl-1-((1R,2R)-4-cyclopropyl-6-fluoro-2-hydroxy-indan-1-yl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridin-3-yl]-benzonitrile (20a).
