Reaction Steps

A solution 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 1-oxime (i.e. the product of Example 2, Step B) (0.10 g, 0.189 mmol), acetyl chloride (0.017 g, 0.22 mmol) and triethylamine (0.022 g, 0.22 mmol) in dichloromethane (5 mL) was stirred for 2 hr and shaken with 1 mL of 1 N hydrochloric acid. The mixture was poured onto a Celite® extraction tube, eluted with dichloromethane and concentrated to give 0.11 g of crude material which was purified via silica gel chromatography (hexanes-ethyl acetate gradient) to provide 0.11 g of the title compound.
