Reaction Steps
A solution of 5-(3-methoxyphenyl)-1-(4-pyridinylmethyl)-2-pyrrolidinone (2.9 g) and 48% hydrobromic acid (40 ml) was heated at 100° C. for 5.5 hrs. The reaction mixture was cooled to ambient temperature, neutralized with saturated sodium bicarbonate solution and extracted with dichloromethane (3 times). The combined organic extracts were dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by flash column chromatography (silica gel, ether/0-20% methanol). The appropriate fractions were collected and concentrated to give 2.3 g (81%) of product. Recrystallization from ether/methanol gave the analytical sample, mp 148°-150° C.
