Procedure
The (4R,5S)-5-bromomethyl-2,2-dimethyl-[1,3]dioxolan-4-carboxylic acid [1-oxo-3-(2-trifluoromethylphenyl)-1,2-dihydroisoquinolin-7-yl]amide (3.0 g, 5.71 mmol) obtained in step B was dissolved in anhydrous DMF (50 ml), and potassium carbonate (3.95 g, 28.6 mmol) was then added thereto. The obtained mixture was stirred at a room temperature for 2 hours. Thereafter, the solvent was distilled away. Water and ethyl acetate were added to the obtained residue. An organic layer was separated, and a water layer was extracted with ethyl acetate. The organic layer was mixed with the extract. The obtained mixture was washed with water and a saturated saline solution, and was then dried over anhydrous sodium sulfate. The solvent was distilled away under reduced pressure. The obtained residue was purified by silica gel column chromatography (methylene chloride:methanol=70:1 to 20:1), so as to obtain 640 mg of 7-((3aR,6aR)-2,2-dimethyl-4-oxotetrahydro-[1,3]dioxolo[4,5-c]pyrrol-5-yl)-3-(2-trifluoromethylphenyl)-2H-isoquinolin-1-one (25%).
