Reaction Steps

A mixture of m-bromophenylacetic acid (4.0 g, 18.6 mmol), t-butyl acrylate (4.85 g, 37.8 mmol), triethylamine (3.8 g, 37.6 mmol), tri-o-tolylphosphine (310 mg, 1.02 mmol) and palladium acetate (130 mg, 0.580 mmol) in N,N-dimethylformamide (50 ml) was stirred for 4 hours at 50° C. and then 10 hours at 90° C. The reaction mixture was diluted with an aqueous sodium hydrogencarbonate solution and washed with ethyl acetate. The aqueous layer was acidified (about pH 3) and extracted with ethyl acetate. The organic layer was washed with an aqueous sodium chloride solution and dried over magnesium sulfate. The solvent was removed under reduced pressure to give the crude subject compound (5.50 g).
