Versuchsvorschrift

To a solution of 6-bromo-2-(4-methanesulfonylbenzyl)-1-oxo-4-phenyl-1,2-dihydroisoquinoline-3-carbaldehyde (500 mg) in THF (10 ml) was added dropwise a solution of ethyl magnesium chloride in THF (2M, 0.61 ml) and the mixture was stirred at room temperature for 10 min. The reaction mixture was added to water and extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the obtained residue was purified by silica gel thin layer chromatography (hexane:ethyl acetate=1:2), followed by crystallization from ethyl acetate-hexane to give the title compound (250 mg).
