実験手順

Triethylamine (5.95 g, 58.9 mmol) was added to a solution of Ethyl 4-(3-(2,6-dimethylbenzyloxy)phenyl)-4-oxo-3-bromo-butyrate (Step D, 2.47 g, 5.8 mmol) in carbon tetrachloride (50 ml). After stirring for 4 hours at room temperature, the reaction mixture was filtered through a pad of silica gel few times, and concentrated to give the title compound.
