A solution of 4-(5-methoxy-1H-indol-3-yl)-cyclohexanone (1.2 g, 5 mmol), 1-(indol-4-yl)piperazine (1 g, 5 mmol), sodium triacetoxyborohydride (1.47 g, 6.2 mmol) and acetic acid (0.28 ml, 4 mmol) in 1,2-dichloroethane (20 ml) was allowed to stir at room temperature overnight. The reaction was quenched with 1N sodium hydroxide (10 ml), extracted with methylene chloride (3×60 ml) and washed with brine (3×60 ml). The organic layer was dried over anhydrous sodium sulfate and filtered. Chromatography (2.5% methanol-ethyl acetate) afforded 1.18 g (55%) of product as a white solid: mp 105-108° C.
