Potassium Acetate → 1-(7-Fluoro-3-methyl-2-(2-(methylsulfonyl)phenyl)quinolin-4-yl)-3,3-dimethyl-2,3-dihydro-1h-pyrrolo[3,2-b]pyridin-6-ylboronic acid

Reaction Steps

A stirred solution of 4-(6-bromo-3,3-dimethyl-2,3-dihydro-1H-pyrrolo[3,2-b]-pyridin-1-yl)-7-fluoro-3-methyl-2-(2-(methylsulfonyl)phenyl)quinoline (93 mg, 0.17 mmol) (described herein) in 1,4-dioxane (2.5 mL) was sparged with N2 for 10 min. After this time bis(pinacolato)diboron (48.1 mg, 0.19 mmol), potassium acetate (25.3 mg, 0.26 mmol), and bis(tricyclohexylphosphine)palladium(o) (11.5 mg, 0.017 mmol) were added and the reaction heated at 100° C. for 16 h. The reaction was cooled to rt and partitioned between EtOAc and water. The organic layer was dried (MgSO4) and concentrated, affording crude 1-(7-fluoro-3-methyl-2-(2-(methylsulfonyl)phenyl)quinolin-4-yl)-3,3-dimethyl-2,3-dihydro-1H-pyrrolo[3,2-b]pyridin-6-ylboronic acid. No further purification was attempted. Mass Spectrum (ESI) m/e=506 (M+1).
