Procedure

To a solution of (S)-5-methyl-piperidine-1,2-dicarboxylic acid 1-tert-butyl ester 2-ethyl ester (1.4 g, 5.16 mmol) in methanol (15 mL) and water (5 mL) was added lithium hydroxide monohydrate (650 mg, 15.48 mmol). The reaction mixture was stirred at RT overnight and concentrated to give the residue, which was extracted with EtOAc/water. The aqueous layer was acidified with 1 N HCl, and extracted with EtOAc to give the organic layer, which was dried and concentrated to give the crude product.
