Reaction Steps

A mixture of 3-(2,6-difluorophenyl)-1-[2-[1-[2-[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl]-4-piperidinyl]-4-thiazolyl]-2-propen-1-one (i.e. the product of Example 2, Step A) (0.25 g, 0.48 mmol), zinc dust (0.25 g, 3.8 mmol) and saturated ammonium chloride (0.25 mL) in ethanol (5 mL) was stirred overnight, concentrated to dryness, treated with dichloromethane and filtered. The filtrate was concentrated and purified via silica gel chromatography (hexanes: ethyl acetate gradient) to provide 0.025 g of 3-(2,6-difluorophenyl)-1-[2-[1-[2-[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl]-4-piperidinyl]-4-thiazolyl]-1-propanone.
