Reaction Steps

To a solution of 3-[(tetrahydro-2H-pyran-2-yloxy)methyl]-5-[3,5-bis(trifluoromethyl)phenyl]isoxazole (Example 323A) (0.590 g, 1.49 mmol) in DCM (15 mL) was added TFA (1.5 mL). The reaction is stirred at rt overnight. Solvent and excess TFA were removed in vacuo. The residue was purified by radial chromatography (0-60% EtOAc-hexanes gradient) to afford the title compound (0.320 g, 69% yield): MS (ES) m/z 312 (M+1).
