To a solution of (S)-methyl 6,6-dimethylmorpholine-3-carboxylate (0.2 g, 1.2 mmol) (The compound was synthesized according to the procedure as described in WO2008024692) in anhydrous methanol (4 mL) was added a solution of sodium hydroxide (0.1 g, 2.4 mmol) in water (1 mL). The reaction mixture was stirred at 25° C. for 2 hours, and cooled to 0° C. The reaction mixture was adjusted to pH 1-2 with con. HCl. The mixture was concentrated in vacuo to give the title compound as a white solid (0.19 g, 100%). The compound was characterized by the following spectroscopic data:

1. temperaturecooled to 0° C
2. concentrationThe mixture was concentrated in vacuo
