Versuchsvorschrift

(RS) 2-Aminomethyl-piperidine-1-carboxylic acid tert butyl ester (0.21 g) and 2-chlorobenzoxazole (0.153 g) and triethylamine (0.1 g) were combined in tetrahydrofuran (10 ml) and stirred at room temperature for 4 hours. The mixture was partitioned between ethyl acetate and water, the organic phase dried and solvent removed at reduced pressure to give the title compound (0.36 g) as an oil that solidified on standing.
