Procedure
Sodium hydride (12.5 mg of a 60% dispersion in mineral oil, 0.31 mmol) was added to a stirred suspension of 4-(5-{5-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-2,3-dihydro-1H-imidazol-4-yl}-1H-pyrazol-1-yl)benzonitrile (Example 1) (102 mg, 0.25 mmol) in THF (5.0 mL) under a nitrogen atmosphere. This resulted in degassing and the formation of a yellow solution. Acetyl chloride (0.022 mL, 0.5 mmol) was added and the mixture was stirred for 1 h then left to stand for 16 h. Water (10 mL) was added and the mixture was extracted with EtOAc (2×10 mL). The combined organic phase was dried (sodium sulfate) and concentrated in vacuo. The residue was purified by flash column chromatography (2 g Si II SPE eluted with DCM then 10% EtOAc in DCM). Concentration of the appropriate fractions in vacua gave the title compound which was freeze-dried from acetonitrile/water to afford a fluffy white solid (56 mg).
