実験手順

To a solution of 4-[1-phenyl-1-(5-(N-(9-fluorenylmethoxycarbonyl)azetidin-3-yl)-1,3,4-oxadiazol-2-yl)methylene]piperidine-1-carboxylic acid tert-butyl ester (0.161 g, 0.260 mmol) and heptanethiol (0.398 mL, 2.60 mmol) in THF (2.6 mL) at rt was added DBU (2 drops). The mixture was allowed to stir for 18 h and then the solvent was removed in vacuo. The residue was dissolved in MeOH and purified by preparative HPLC(NH4OAc) to afford the title compound (0.077 g, 74%) as a colorless solid:
