Procedure

To 40 mg of 1-benzoyl-4-(2-benzyloxazol-5-yl)piperidine (step F) in 4.5 mL methanol and 0.5 mL water was added 260 mg of potassium hydroxide. The reaction was stirred at 80° C. overnight, 20 mL of water was added and the mixture was extracted with 3×20 mL ethyl acetate. The combined organic layers were dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give 22 mg of the title compound.
