To a solution of tert-butyl 2-(7-hydroxy-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetate (0.045 g, 0.157 mmol) in DMA (1 mL) was added Cs2CO3 (0.0.077 g, 0.235 mmol) followed by 4-(chloromethyl)-1-(cyclohexylmethyl)-2-(trifluoromethyl)benzene (0.050 g, 0.172 mmol). The reaction was stirred at 60° C. for 16 h. The mixture was filtered. The filtrate was concentrated under vacuum and purified by silica gel column chromatography to give the title compound as a white solid (0.053 g).
