Procedure
Racemic 3-(1-{4-[4-(trifluoromethoxy)phenyl]-1H-imidazol-2-yl}ethyl)oxetan-3-amine (Example 9, 0.243 g, 0.743 mmol) was dissolved in ethanol (1 mL). Enantiomers were separated by chiral preparative HPLC under basic conditions at ambient temperature on a Chiralpak AD-H column (250*, 20 mm i.d) supplied by Daicel Chemical Industries. A flow rate of 18 mL/min was used with mobile phase A: heptane and B: IPA+0.1% diethylamine (v/v). Two Agilent 1200 prep pumps supplied a mobile phase with a composition of 20% B. Run time was 10 minutes per 0.1 mL injection volume. Detection was achieved using an Agilent 1200 multiple wavelength UV absorbance detector set at 220 nm.
