실험 절차

A solution of 0.2 g (0.47 mmol) [5-(tetrahydro-pyran-4-yl)-1,3-dihydro-isoindol-2-yl]-[2-((S)-2,2,2-trifluoro-1-methyl-ethoxy)-phenyl]-methanone in 2 ml of 1,2-dichloroethane was added dropwise to 0.32 ml (4.7 mmol) chlorosulfonic acid under ice bath cooling. The mixture was stirred at room temperature for 30 minutes and then at 55° C. for 30 minutes. The mixture was cooled in an ice bath and quenched by dropwise addition of 2 ml water. The mixture was diluted with dichloromethane. The organic layer was separated and the aqueous layer was extracted twice with dichloromethane. The combined dichloromethane extracts were dried over Na2SO4, filtered and concentrated in vacuo. The obtained foam was stirred with ethylacetate. The solid was filtrated. The filtrate was washed twice with a saturated solution of NaHCO3, dried over Na2SO4, filtered and concentrated in vacuo to provide 0.12 g (51%) of the title compound as light yellow foam. MS (m/e): 517.1 [M]+.
