Conditions

Temperature
100 °C

Procedure

(RS)-2-Aminomethyl-piperidine-1-carboxylic acid tert butyl ester (0.25 g) and 2-chlorobenzimidazole (0.15 g) were combined and warmed to 100° C. for 48 hours. After cooling to room temperature the mixture was column chromatographed (silica gel, ethyl acetate/pentane 1:4—ethyl acetate/pentane 1:1 eluant) to give the title compound (0.1 g).
