Reaction Steps

To a solution of 3-chloro-1-phenylpyrrolidin-2-one (100 mg, 0.51 mmol) in EtOH (10 mL) was added 1-(2-methylbenzothiazol-5-yloxy)-3-piperazin-1-ylpropan-2-ol as prepared in Example 3A (190 mg, 0.62 mmol) and Et3N (0.2 mL, 1.43 mmol). The solution was stirred at 85° C. for 60 hours. Upon cooling, the solution was concentrated to an oil and purified via flash column chromatography to afford 3-{4-[(2R)-2-hydroxy-3-(2-methylbenzothiazol-5-yloxy)propyl]piperazinyl}-1-phenylpyrrolidin-2-one.
