Participants

Reaction Steps

Thionyl chloride (0.24 ml, 3.25 mmol, 1.5 eq) is added into a cold solution of 4-(hydroxymethyl)-1-{4-[3-(2-methylpyrrolidin-1-yl)propoxy]phenyl}pyrrolidin-2-one 72 (0.78 g, 2.16 mmol, 1 eq) and triethylamine (0.3 ml, 2.16 mmol, 1 eq) in dichloromethane (30 ml). The mixture is warmed to room temperature and stirred overnight. The solution is washed once with water and once with a saturated solution of aqueous sodium chloride. The organic layer is dried over magnesium sulfate and concentrated under vacuum to give 0.54 g of 4-(chloromethyl)-1-{4-[3-(2-methylpyrrolidin-1-yl)propoxy]phenyl}pyrrolidin-2-one a56 as a dark-red oil.
