Procedure

A solution of 2-carboxymethyl-piperidine-1-carboxylic acid tert-butyl ester (Beckett et al, J. Med. Chem., 563,1969) (2.29 g, 10 mmol) in DMF (20 ml) was treated sequentially with N,N-diisopropylethylamine (4.0 ml), HATU (3.8 g, 10 mmol) and O,N-dimethyl-hydroxylamine.HCl (0.98 g, 10 mmol). The reaction mixture was stirred under argon at room temperature for 16 h. The volatiles were removed in vacuo and the residue was chromatographed (silica gel, diethyl ether) to afford the title compound as a white solid (2.60 g, 90%).
