Procedure

3-[3-(2-Pyridinyl)-1,2,4-oxadiazol-5-yl]propanoic acid (0.60 g) was dissolved in dichloromethane (10 ml). 1,1-Carbonyldiimidazole (0.33 g) was added followed by tert-butyl 4-amino-1-piperidinecarboxylate hydrochloride (0.5 g) and triethylamine (0.31 ml). After 2 hours water, brine and dichloromethane were added and the phases separated. The organic phase was dried, filtered and evaporated and the residue was purified by chromatography eluting with ethyl acetate:methanol (33:1) to give the subtitle compound (0.40 g).
