A solution of (3S,4R)-3-[(R)-1-Phenyl-ethylamino]-tetrahydro-pyran-4-carboxylic acid ethyl ester (726 mg, 2.6 mmol) in tetrahydrofuran (6 mL) was treated with 1.0 M sodium hydroxide solution (5.2 mL, 5.2 mmol) and the heterogeneous mixture was stirred at room temperature. After 16 h, the now homogeneous solution was treated with 1.0 M hydrochloric acid (5.2 mL, 5.2 mmol) and concentrated in vacuo. The residue was dissolved in water and lyophilized to provide the product, along with sodium chloride, as a fluffy white solid (943 mg, quantitative), used without further purification.
