Reaction Steps

A mixture of 4-bromo-7-chloro-3-(4-chloro-benzenesulfonyl)-quinoline (0.42 g, 1 mmol), 4-fluorophenylboronic acid (0.21 g, 1.5 mmol) and tetrakis-(triphenylphosphin)palladium(0) (0.08 g, 0.07 mmol) in 30 ml 1,2-dimethoxyethane and 8 ml of 2M aqueous sodium carbonate solution was stirred for 2 hours at 70° C. After cooling the mixture was concentrated in vacuo. The crude residue was purified by column chromatography on silica gel (Kieselgel 60, eluent: chloroform) and crystallized from methanol to obtain 0.29 g of the title compound in 67% yield.
