Procedure

To a mixture of 5-(2-benzyloxy-4-iodophenyl)-1,1-dioxo-1,2,5-thiadiazolidin-3-one (2.0 g, 4.49 mmol), Pd(OAc)2 (100 mg) and acrylic acid t-butyl ester (0.78 mL, 5.8 mmol) in acetonitrile (15 mL) in a pressure vessel is added triethylamine (3.13, 22.5 mmol) and the mixture is stirred at 100° C. for 6 h. The solution is filtered through Celite, washed with acetonitrile and concentrated to give the title compound. This is used directly in the next step.
