To a solution of 2-(4-fluorophenyl)-1-[4-morpholin-4-yl-2-(2-phenoxy-pyrimidine-4-carbonyl)pyrazolidine-1-yl]ethanone, 19, (0.2 g, 0.4 mmol) in DMF (10 mL) at 0° C. is added NaH (0.024 g, 0.6 mmol) and the resulting solution is stirred 2 hours. The solvent is removed in vacuo the residue dissolved in methylene chloride and extracted with water, dried, and re-concentrated to afford 37 mg (20% yield) of the desired product as a yellow solid.
