Reaction Steps

1-[2-(4-Morpholinyl)ethyl]-2-(3-methoxyphenyl) pyrrolidine (3.6 g) in 48% hydrobromic acid (50 ml) was heated at 100° C. for 8.5 hrs. The reaction mixture was cooled to ambient temperature, neutralized with saturated sodium bicarbonate solution and diluted with dichloromethane. The layers were separated and the aqueous phase was extracted with dichloromethane (3 times). The combined organic extracts were washed with brine, dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by flash column chromatography (silica gel, ether). The appropriate fractions were collected and concentrated to give 2.0 g (59%) of 3-{1-[2-(4-morpholinyl)ethyl]-2-pyrrolidinyl}phenol.
