Reaction Steps

0.577 g (2.200 mmol) triphenylphosphine was added batchwise to a suspension of 0.836 g (2.000 mmol) (E)-N-[3-chloro-4-(3-hydroxy-propyl)-phenyl]-3-(2-chloro-4-trifluoromethyl-phenyl)-acrylamide and 0.730 g (2.200 mmol) tetrabromomethane in 10 mL dichloromethane and the mixture was stirred for 48 h at RT. The reaction mixture was purified by column chromatography (silica gel, dichloromethane) and the residue was triturated with petroleum ether.
