Sodium hydride → 2-(10-methyl-2,3,5,6-tetrahydro-1H-pyrido[3',2':4,5]pyrrolo[2,3-g]indolizin-7(11cH)-yl)-1-(piperidin-1-yl)ethanone

Reaction Steps

To a solution of 10-methyl-2,3,5,6,7,11c-hexahydro-1H-pyrido[3′,2′:4,5]pyrrolo[2,3-g]indolizine (80 mg, 0.352 mmol) in DMF (1 mL) was added a suspension of sodium hydride (42 mg, 1.05 mmol) in DMF (1 mL). After stiffing for 5 min at RT, a solution of 2-chloro-1-(piperidin-1-yl)ethanone (114 mg, 0.704 mmol) in DMF (1 mL) was added to the reaction mixture, and stiffing continued for 16 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-(10-methyl-2,3,5,6-tetrahydro-1H-pyrido[3′,2′:4,5]pyrrolo[2,3-g]indolizin-7(11cH)-yl)-1-(piperidin-1-yl)ethanone;
