Procedure

A solution of 3-[2-(tert-butoxycarbonyl-pyridin-4-yl-amino)-ethoxy]-5-chloro-benzoic acid (0.040 g), cyclopentyl-(2-[1,2,4]triazol-1-yl-ethyl)-amine (0.05 g) and EEDQ (0.040 g) in acetonitrile (2 ml) was stirred at reflux, under nitrogen, for 2 h. The solvent was evaporated and the residue was purified by flash chromatography eluting with dichloromethane:methanol (95:5 v/v) to give the title compound as a yellow oil (0.022 g).
