실험 절차

To a solution of 7,8,9,9a,10,11-hexahydro-5H-pyrido[3′,2′:4,5]pyrrolo[3,2-f]indolizine (70 mg, 0.32 mmol) in DMF (1 mL) was added a suspension of NaH (40.0 mg, 0.986 mmol) in DMF (1 mL). After stirring for 5 min at RT, a solution of 2-chloro-1-(piperidin-1-yl)ethanone (159 mg, 0.986 mmol) in DMF (1 mL) was added dropwise into the reaction mixture and stiffing continued for another 3 h. The progress of reaction was monitored by TLC and NMR. The reaction mixture was diluted with ice-water (20 mL) and extracted with EtOAc (3×25 mL). The organic layer was washed with water (3×20 mL), dried over anhydrous sodium sulfate and concentrated under reduced pressure to afford crude material, which was purified by silica gel flash chromatography (10% MeOH-DCM) to yield 1-(piperidin-1-yl)-2-(8,9,9a,10-tetrahydro-5H-pyrido[3′,2′:4,5]pyrrolo[3,2-f]indolizin-11(7H)-yl)ethanone;
