Procedure
Methanolic hydrogen chloride (3M, 20 mL) was added over 10 minutes to a stirred, cooled (0° C.) solution of 1,1-dimethylethyl 1-oxa-8-azaspiro[4.5]decane-8-carboxylate (Description 74, 3.18 g, 13.2 mmol) in methanol (10 mL) and the mixture was stirred at room temperature for 3 hours. The solvent was evaporated under reduced pressure to give the title compound (2.29 g, 98%). m/z (ES+) 142 (M+1).
Workup
- customThe solvent was evaporated under reduced pressure
