The reaction solution is stirred at room temperature overnight. After concentration using a rotary evaporator and oil pump vacuum at 40° C., the residue is purified using an SiO2 cartridge (n-heptane; n-heptane/ethylacetate 4:1). The product is obtained as an oil. C32H36F2INO3 (647) MS (ESI): M+−18
