Procedure

To a solution of 10-methyl-2,3,5,6,7,11c-hexahydro-1H-pyrido[3′,2′:4,5]pyrrolo[2,3-g]indolizine (110 mg, 0.484 mmol) in DMF (1 mL) was added a suspension of NaH (60.0 mg, 1.45 mmol) in DMF (1 mL). After stirring for 5 min at RT, a solution of 2-(6-methylpyridin-3-yl)ethyl 4-methylbenzenesulfonate (423 mg, 1.45 mmol) in DMF (1 mL) was added dropwise into the reaction mixture and stirring continued for another 2 h. The progress of reaction was monitored by TLC and LCMS. The reaction mixture was diluted with 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 reverse phase HPLC to yield 10-methyl-7-(2-(6-methylpyridin-3-yl)ethyl)-2,3,5,6,7,11c-hexahydro-1H-pyrido[3′,2′:4,5]pyrrolo[2,3-g]indolizine;
