[Step 3] To a solution (40 ml) of 2-benzoyl-4-bromo-N-(4-methanesulfonylbenzyl)-N-(2-oxopentyl)benzamide (2.0 g) in toluene was added 1,8-diazabicyclo[5.4.0]undeca-7-ene (1.1 g), and the mixture was heated under reflux for 48 hrs. The reaction mixture was concentrated under reduced pressure. To the residue were added water and 10% hydrochloric acid, and the mixture was extracted with ethyl acetate. The organic layer was washed with water, saturated aqueous sodium hydrogen carbonate, water and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by recrystallization (THF-diisopropyl ether) to give the title compound (1.4 g).
