A mixture of 1-bromo-3-iodobenzene (3 g) and 1,1′-bis(diphenylphosphino)ferrocene (90 mg) in dimethylformamide (10 ml) and triethylamine (2 ml) was treated with tris(dibenzylideneacetone)dipalladium (175 mg) at 20° C. under nitrogen. After 10 min ethyl 3-mercaptopropionate (1.14 ml) was added and the mixture was heated to 60° C. for 1.5 h. The mixture was diluted with ethyl acetate and washed with 2M hydrochloric acid, brine and dried (MgSO4). The filtrate was concentrated and chromatographed on a biotage cartridge (40 g) eluting with dichloromethane-cyclohexane (1:3) to give the title compound (1.58 g) LCMS RT=3.50 min
