Reaction Steps

A suspension of 5-bromo-6-chloro-1H-indole-3-carboxylic acid (100 mg, 0.54 mmol), 2-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)-5-(1-hydroxycyclobutyl)benzonitrile (124 mg, 0.435 mmol), 0.5M aqueous potassium phosphate (1.74 mL, 0.87 mmol) and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (11 mg, 0.014 mmol) in ethanol (4 mL) was sealed in a microwave tube and heated to 85° C. for 45 minutes. The reaction was diluted with water and extracted with ethyl acetate (2×10 mL). The reaction mixture was filtered through celite and the phases were separated. The organic phase was dried over sodium sulfate, filtered and concentrated in vacuo and the residue was purified by reverse phase chromatography to give the title compound. MS (ES−) 365.1 (M−H)−. Retention time: 1.60 min. Column: Waters Atlantis dC18 4.6×50 mm, 5 μm. Modifier: TFA 0.05%. Gradient: 95% H2O/5% MeCN linear to 5% H2O/95% MeCN over 4.0 min, HOLD at 5% H2O/95% MeCN to 5.0 min. Flow: 2.0 mL/min.
