To a solution of hexahydro-1H-furo[3,4-c]pyrrole (0.15 g) in acetone (50 mL) was added K2CO3 (0.46 g) and 1-chloro-3-bromopropane (0.42 g, 2.0 eq) in turn. The reaction mixture was heated to reflux for 12 h and filtered. The filtrate was concentrated in vacuo and the residue was dissolved in EtOAc (100 mL). The solution was washed with water twice followed by brine once. The solution was dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was chromatographed with a silica gel column (eluting agent: 20:1 (v/v) EA/CH3OH) to give the title compound (0.13 g, 50.04%). The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 190.7 (M+1).
