Procedure

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) and powdered KOH (138 mg, 2.46 mmol) in NMP (2 mL) was stirred at RT for 5 min. 2-(Trifluoromethyl)-5-vinylpyridine (122 mg, 0.704 mmol) was added into the reaction mixture and stirring 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 10-methyl-7-(2-(6-(trifluoromethyl)pyridin-3-yl)ethyl)-2,3,5,6,7,11c-hexahydro-1H-pyrido[3′,2′:4,5]pyrrolo[2,3-g]indolizine;
