실험 절차

Combine 2-(4-cyclopropanesulfonyl-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (200 mg, 0.65 mmol), the compound of Preparation 1 (150 mg, 0.28 mmol) and cesium fluoride (214 mg, 1.4 mmol) in dried flask fitted with a reflux condenser. In a separate flask combine palladium (II) acetate (6.2 mg, 0.028 mmol) and tricyclohexylphosphine (11.7 mg, 0.042 mmol). Add acetonitrile (3.0 mL) and sonicate for 10 minutes under nitrogen. Add the catalyst solution to the solids and heat in an 80° C. oil bath for 20 minutes. Cool the suspension to room temperature and filter through packed celite. Rinse the celite with acetonitrile and evaporate. Chromatograph the residue on a SiO2 column eluting the material with methanol in dichloromethane (0 to 5%) to give 120 mg of the title compound (77%). Mass spectrum (ion spray): m/z 558.3 (M+H).
