実験手順

1-Bromo-5-(1,1-dimethoxyethyl)-2-methoxy-3-trifluoromethylbenzene (O3.004; 700 mg) was initially charged in dioxane (7 ml) and admixed successively with Pd(II) acetate (46 mg), cesium carbonate (2 g), 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (118 mg) and morpholine (0.27 ml). Thereafter, the reaction mixture was heated to 90° C. for 7 h and then left to stand overnight. Subsequently, it was filtered and the filtrate was concentrated by rotary evaporation. The residue was purified using silica gel (50 g cartridge, n-heptane/EA gradient). 433 mg of the title compound were obtained.
