Procedure

A solution of 2,3,5,6,7,11c-hexahydro-1H-pyrido[3′,2′:4,5]pyrrolo[2,3-g]indolizine (120 mg, 0.565 mmol) and powdered KOH (221.5 mg, 3.955 mmol) in NMP (2 mL) was stirred at RT for 10 min. 2-(Trifluoromethyl)-5-vinylpyridine (195.5 mg, 1.13 mmol) was added into the reaction mixture and stiffing continued for 24 h at RT. 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 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;
