Versuchsvorschrift

A solution of (±)-1,1,1-trifluoro-2-(2-mercapto-1,3-thiazol-5-yl)butan-2-ol (1.2 g) from step 2 of example 1 in EtOH/hexane (20 ml, 1:4) was injected (1×1.2 g) onto a CHIRALPAK AD preparative (5 cm×50 cm) HPLC column (eluting with hexane/EtOH, 4:1; at 75 ml/min with UV detection at 280 nm). The enantiomers were separated with the faster eluting enantiomer having a retention time of ˜19 min (enantiomer #1, (2S)-1,1,1-trifluoro-2-(2-mercapto-1,3-thiazol-5-yl)butan-2-ol) and the slower eluting enantiomer having a retention time of ˜34 min (enantiomer #2, (2R)-1,1,1-trifluoro-2-2-mercapto-1,3-thiazol-5-yl)butan-2-ol). The eluants were concentrated to provide enantiomer #1 (0.468 g, 99% ee) and enantiomer #2 (0.426 g, 98% ee).
