Procedure

To a solution of 2.00 g (5.20 mmol) 4-(2-bromo-phenyl)-piperidine-1,4-dicarboxylic acid mono-tert-butyl ester in 26 ml dichloromethane were added 0.76 ml (5.73 mmol) 1-chloro-N,N,2-trimethylpropenylamine at room temperature. After stirring for 45 min the reaction mixture was concentrated in vacuo. The residual oil was redissolved in 26 ml dry N,N-dimethylformamide and treated with 0.51 g (7.8 mmol) sodium azide. After stirring for 1 h the reaction mixture was diluted with 200 ml tert-butyl methyl ether and washed with 0.5 M aqueous sodium carbonate solution (2×50 ml). The combined aqueous layers were extracted with tert-butyl methyl ether (2×100 ml). The combined organic layers were washed with water (1×50 ml) and brine (1×50 ml), dried over sodium sulfate and concentrated in vacuo to give the crude title compound (1.76 g, 83%) as a light yellow solid.
