Procedure

To a solution of 3-methyl-7,8,9,9a,10,11-hexahydro-5H-pyrido[3′,2′:4,5]pyrrolo[3,2-f]indolizine (100 mg, 0.440 mmol) in DMF (1 mL) was added a suspension of sodium hydride (52 mg, 1.32 mmol) in DMF (1 mL). After stirring for 5 min at RT, a solution of 2-chloro-1-(piperidin-1-yl)ethanone (142 mg, 0.881 mmol) in DMF (1 mL) was added to the reaction mixture, and stirring continued for 2 h. The reaction mixture was diluted with water and extracted with EtOAc. The organic layer was washed with water, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue obtained was purified by silica gel flash chromatography to yield 2-(3-methyl-8,9,9a,10-tetrahydro-5H-pyrido[3′,2′:4,5]pyrrolo[3,2-f]indolizin-11(7H)-yl)-1-(piperidin-1-yl)ethanone;
