Reaction Steps

(Bromomethyl)cyclopropane a48 (47 μl, 0.48 mmol, 2.1 eq) is added to a solution of (5S)-5-{[(cyclohexylmethyl)amino]methyl}-1-[4-(3-piperidin-1-ylpropoxy)phenyl]pyrrolidin-2-one 2 in acetonitrile (4 ml), then cesium carbonate (150 mg, 0.46 mmol, 2 eq) and potassium iodide (8 mg, 0.05 mmol, 0.2 eq) are added and the mixture is heated at 50° C. for 24 h. The precipitate is filtered and the solvent is removed in vacuo. The residue is dissolved into dichloromethane and washed with a saturated solution of aqueous ammonium chloride. The aqueous layer is then extracted with dichloromethane, the organic layers are dried over magnesium sulfate and concentrated in vacuo to give 109 mg of a yellow oil. This oil is purified by chromatography over silicagel (dichloromethane/methanol/ammonia 92/8/0.8) to obtain 47 mg of (5S)-5-{[(cyclohexylmethyl)(cyclopropylmethyl)amino]methyl}-1-{4-[3-(2-methylpyrrolidin-1-yl)propoxy]phenyl}pyrrolidin-2-one 3 as a yellow oil.
