Procedure

Under a nitrogen atmosphere 30.0 g (136.7 mmol) 5-bromo-2-chloro-1,3-dimethylbenzene, 24.0 g (164.0 mmol) methyl 2-acetylamino-acrylate in 420 mL triethylamine and 200 mL acetonitrile were combined with 3.4 g (10.9 mmol) tri-o-tolyl-phosphane and 2.4 g (10.9 mmol) Pd(OAc)2 and stirred for 18 h at 80° C. The precipitate was suction filtered, the filtrate was evaporated down i. vac., combined with 800 mL DCM and 800 mL water, the organic phase was separated off and dried over Na2SO4. After the desiccant and solvent had been eliminated the residue was stirred with EtOAc, suction filtered and dried i. vac.
