3-(2-Bromophenoxy)pyrrolidine (1.23 g), 1-bromo-2-methoxyethane (0.526 ml) and potassium carbonate (842 mg) were mixed with dimethylformamide (50 ml) and stirred for two days. The mixture was added to water (100 ml). The mixture was extracted with diethyl ether (3×50 ml), washed with water (2×50 ml), brine (2×30 ml), dried (MgSO4) and concentrated in vacuo. Purification was achieved using cation exchange chromatography eluting with ammonia/methanol/dichloromethane mixtures yielding product as a clear oil (0.8 g).
