Methanol → Tert-butyl(3-phenylpropyl)(piperidin-4-yl)carbamate

Participants

Reaction Steps

To 2 mL of a methanol solution containing 0.60 g of tert-butyl(3-phenylpropyl)(1-(trifluoroacetyl)piperidin-4-yl)carbamate, 0.4 mL of water was added, and 0.28 g of potassium carbonate was added under cooling with ice, and the mixture was stirred at the same temperature for 2 hours and 10 minutes and at room temperature for 2 hours and 15 minutes. Thereto was added 2 mL of methanol and 0.5 mL of water, and the mixture was left to stand at room temperature overnight. The solvent was removed under reduced pressure, and the residue thus obtained was added with ethyl acetate and water. The organic layer was separated, washed with an aqueous saturated sodium chloride solution and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to obtain 0.45 g of a colorless oily substance, tert-butyl(3-phenylpropyl)(piperidin-4-yl)carbamate.
