実験手順

To 6-(4-bromo-3-(pyridin-4-yl)-1H-pyrazol-1-yl)nicotinonitrile (0.26 g; Example 6, step 1) in 16 mL acetonitrile and 4 mL water was added (E)-1-(benzyloxyimino)-2,3-dihydro-1H-inden-5-ylboronic acid (0.34 g; Example 2, Step 4) and 0.33 g potassium carbonate. The reaction mixture was purged with nitrogen and 46 mg tetrakis(triphenyphosphine)palladium(0) catalyst was added. The reaction mixture was heated to 80° C. for 1.5 hours, filtered through celite, the filter cake was washed with acetonitrile. The filtrate was evaporated to yield crude product, which was purified by chromatography, eluting with a 10:1 mixture of dichloromethane-methanol to afford 0.15 g (36% yield) product as a pale yellow solid. 1H NMR (CDCl3) was consistent with the desired structure. LC/MS showed one peak with a M+1 molecular ion of m/z 483.2 by positive ESI.
