Reaction Steps

The mixture containing 1-bromo 5-fluoro 2-nitrobenzene (1 g, 4.5 mmol), 2,4-dichloro benzeneboronicacid (907 mg, 4.7 mmol), sodiumcarbonate (1.44 g, 13.5 mmol) in benzene and 3 ml of water was purged with nitrogen for 30 mins. Tetrakis(triphenylphosphine)-palladium(0) (264 mgs, 0.2 mmol) was added to the mixture and was heated to 75° C. overnight. The reaction mixture was partitioned between ethyl acetate and water. Organic layer was separated and washed with brine, dried (MgSO4), filtered and concentrated in vacuo to give a brown solid which was recrystallized to give 1 g (yield, 80%) of white solid. The product gave satisfactory NMR.
