Procedure

A solution 2-(6-fluorochroman-8-yloxy)ethylchloride (0.25 g, 7.1 mmol), 3-(5-fluoro-1H-indol-3-yl)-propylamine (0.42 g, 2.2 mmol) and triethylamine (0.22 g, 2.2 mmol) in anhydrous dimethylsulfoxide (20 ml) was allowed to stir for 14 hours at 90° C. The mixture was poured into water (100 ml) and extracted with methylene chloride (3×100 ml). The organic layer was washed with water (3×150 ml), dried over anhydrous sodium sulfate, filtered and the solvent was removed under vacuum. Chromatography (10% methanol-methylene choride plus ammonium hydroxide) afforded 0.25 g (60%) as a white solid: mp 137-138.5° C.
