実験手順

1-(1-Methylethyl)-N-[2-(tetrahydro-2H-pyran-2-yl)-6-(4,4,6,6-tetramethyl-1,3,2-dioxaborinan-2-yl)-2H-indazol-4-yl]-1H-pyrazole-5-carboxamide (49 mg, 0.1 mmol) was dissolved in 1,4-Dioxane (0.4 mL) and added to 4-bromo-1H-indole-6-carbonitrile (22 mg, 0.1 mmol, available from Sinova) in a microwave vessel. 1,4-Dioxane (0.4 ml) was added followed by chloro[2′-(dimethylamino)-2-biphenylyl]palladium-(1R,4S)-bicyclo[2.2.1]hept-2-yl[(1S,4R)-bicyclo[2.2.1]hept-2-yl]phosphane (1:1) (Solvias catalyst, 2 mg, 0.004 mmol, (heaped microspatula) available from ABCR) and a solution of potassium triphosphate (0.2 g, 0.1 mmol) in water (0.2 ml). The vessel was sealed and heated in CEM Discover using initial 150 W to 110° C. for 20 min. After cooling the solution was loaded onto a C18 SPE cartridge (pre-conditioned with MeCN/0.1% TFA) and flushed through with a further 3 ml MeCN/0.1% TFA. Solvent was removed by blowdown under a stream of nitrogen. The residue was dissolved in MeOH (0.5 ml) and loaded onto a SCX-2 SPE cartridge (1 g) pre-conditioned with MeOH. The material was left on the column for 1 hr then eluted with 2M ammonia/MeOH and evaporated to dryness. The sample was purified by Mass Directed AutoPrep (Method C) to afford the title compound (6.4 mg).
