Acetyl chloride → HCID 57550254, compound

Participants

Reaction Steps

Acetyl chloride (0.51 ml, 0.72 mmol, 1.2 eq) is added to a cooled (ice bath) solution of (5S)-5-(aminomethyl)-1-{4-[3-(2-methylpyrrolidin-1-yl)propoxy]phenyl}pyrrolidin-2-one 113 (0.2 g, 0.6 mmol, 1 eq) in dichloromethane (12 ml). The mixture is stirred 2 hours at room temperature, washed with a saturated solution of sodium bicarbonate and with brine, dried over magnesium sulfate and concentrated under vacuum to give 0.158 g of yellow oil. The crude material is purified by two chromatographies over silicagel (first one: gradient dichloromethane/methanol/ammonia 100:0:0 to 88:12:1.2; second one: dichloromethane/methanol/ammonia 80:20:2).
