Procedure

Piperidine-1,4-dicarboxylic acid mono-tert-butyl ester (1.0 eq, 21.8 mmol) was dissolved under inert conditions in 35 ml dry N,N-dimethylformamide. O,N-dimethyl-hydroxylamine hydrochloride (1.03 eq, 22.5 mmol), benzotriazol-1-ol monohydrate (1.03 eq, 22.5 mmol) and triethylanine (1.5 eq, 32.7 mmol) were added. The reaction mixture was cooled to 0° C., N-(3-Dimethylaminopropyl)-N-ethylcarbodiimid hydrochloride (1.0 eq, 21.8 mmol) was added over a period of 1.0 minutes and the mixture was stirred vigorously at 0° C. for 1 h and at r.t. for 18 h.
