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) and methoxyamine hydrochloride (0.047 g, 0.58 mmol) in methanol (10 mL) was heated overnight at 60° C. The reaction was concentrated under reduced pressure, partitioned between dichloromethane and saturated sodium bicarbonate. The mixture was eluted from a Celite® extraction tube (ChemElute® diatomaceous earth-based liquid-liquid exchange cartridge) with dichloromethane and concentrated to provide 0.26 g of the title compound.
