反応手順
6-Bromo-3-methanesulfonyl-2-methyl-4-morpholin-4-yl-quinoline (compound of example 6) (0.5 g, 1.3 mmol), cyclopropyboronic acid (0.167 g, 1.95 mmol), potassium phosphate tribasic (0.826 g, 3.89 mmol) and tetrakis(triphenylphosphine)palladium(0) (45 mg, 0.039) were mixed together in dioxane (7 mL) and heated at reflux under argon for 8 h. After extraction with dichloromethane and half-saturated NaCl solution, the crude product was purified chromatography on silica gel in dichloromethane/ethyl acetate with a gradient from 100:0 to 90:10. One obtained 0.1 g (21%) of white crystals. MS: m/z=347 (M+H).
