A solution tetrabutylammonium fluoride (1M in THF) was added drop wise to a 0° C. solution of (S)-4-(4-Fluoro-phenyl)-6-oxo-1,4,5,6-tetrahydro-pyridine-3-carboxylic acid (5-{1-[2-(tert-butyl-dimethyl-silanyloxy)-ethyl]-5-methyl-1H-pyrazol-3-yl}-2-methyl-phenyl)-amide (66 mg) in THF. The mixture was stirred at 0° C. for five minutes and then stirred at room temperature for 18 hours. The mixture was partitioned between water and EtOAc. The organic layer was washed with water and brine, dried over Na2SO4, filtered, and concentrated to dryness under reduced pressure. Purification of the crude product by flash chromatography (0 to 8% CH3OH in CH2Cl2) gave 24 mg of (S)-4-(4-fluoro-phenyl)-6-oxo-1,4,5,6-tetrahydro-pyridine-3-carboxylic acid {5-[1-(2-hydroxy-ethyl)-5-methyl-1H-pyrazol-3-yl]-2-methyl-phenyl}-amide as a solid, MS (M+H)=419.
