Procedure: 1-(3-Chlorophenyl)-1-buten-3-one (20.0 g, 111 mmol) was subjected to hydrogen catalytic reduction in ethanol (200 ml) at room temperature by using platinum oxide (PtO2; 0.30 g) as a catalyst. The catalyst was filtered off and the resulting filtrate was concentrated under reduced pressure. The resulting residue was purified by a silica gel column chromatography to obtain 11.1 g of 1-(3-chlorophenyl)butan-3-one. The catalyst was filtered off the resulting filtrate was concentrated under reduced pressure The resulting residue was purified by a silica gel column chromatography

Procedure: Prepared according to the procedure described in Example 24, Step 1, using 5-(4-bromo-phenyl)-3-methyl-isoxazol-4-ylamine and 4-(3-chloro-phenyl)-butan-2-one. After silica gel chromatography the crude material was purified via preparatory chiral HPLC (Chiralcel-AD column, 1% EtOH in hexanes, 36 minutes) to afford two separate enantiomers. The first enantiomer eluted from the column is the title compound.
