Reaction Steps

5-Bromo-7-fluoro-1,3,3-trimethyl-1,3-dihydro-2H-indol-2-one (0.10 g, 0.36 mmol), 1-methyl-5-cyano-2-pyrroleboronic acid (95 mg, 0.63 mmol), KF (69 mg, 1.19 mmol) were suspended in 1 mL of dioxane. Pd2(dba)3 monochloroform adduct (3.1 mg, 0.003 mmol) and Pd(P(t-Bu)3)2 (4.6 mg, 0.009 mmol) were added and the mixture was stirred vigorously at 45° C. for 6 h. The mixture was diluted with 100 mL of EtOAc and filtered through a plug of silica gel and concentrated. Purification by flash chromatography (2% acetone/hexane) afforded the title compound (30 mg, 28%) as a tan solid.
