Versuchsvorschrift

To a solution of 1-[2-(5-{1-[4-(cyclopropylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrol-2-yl)-1,3-thiazol-5-yl]ethanol (300 mg) in tetrahydrofuran (5 mL) was added N-chlorosuccinimide (82.3 mg) at 0° C., and the mixture was stirred at 50° C. overnight. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate, and washed with saturated aqueous sodium hydrogen carbonate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4) and concentrated. The residue was subjected to preparative HPLC to give a mixture of the title compound and a positional isomer thereof (210 mg). The mixture of the obtained positional isomers was dissolved in hexane-2-propanol (700:300, volume ratio, 18.8 mL), and the solution was subjected to HPLC using CHIRALPAK AD (50 mmID×500 mL, manufactured by DAICEL CHEMICAL INDUSTRY LTD.). Using hexane-2-propanol (700:300, volume ratio) as a mobile phase, the solution was eluted at flow rate 60 mL/min and at 30° C., and the fraction was separated at retention time 22.0 min, and concentrated. The obtained solid was dissolved in ethyl acetate and the insoluble material was filtered off. The filtration was concentrated to give the title compound (85.9 mg, yield 27%) as a colorless amorphous solid. MS: 521 (MH+).
