실험 절차

A mixture of 1-[2-[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl]-4-piperidine-carbothioamide (i.e. the product of Example 8, Step C) (1.7 g, 5.0 mmol) and 2-bromo-1-[(5R)-4,5-dihydro-5-phenyl-3-isoxazolyl]ethanone (i.e. the product of Example 12, Step E) (1.35 g, 5 mmol) in ethanol (15 mL) was heated at 50° C. for 30 minutes. The reaction mixture was diluted with water and extracted with dichloromethane. The extract was washed with brine, dried (MgSO4), and concentrated under reduced pressure to give the title product as a pale-yellow gum. High performance liquid chromatography (HPLC) analysis showed that the title product was about 95% pure and contained the (R)-enantiomer in about 98% enantiomeric excess.
