Sodium Bicarbonate → HCID 66755647, compound

Participants

Reaction Steps

6.23 g (26.8 mmol) of benzylbis(2-chloroethyl)amine hydrochloride were dissolved in ethanol (100 ml) and, while stirring, 5.00 g (26.8 mmol) of (S)-(−)-N-Boc-3-aminopyrrolidine and 9.02 g (107 mmol) of sodium bicarbonate were added. The resulting reaction solution was heated under reflux for 4 h. The cooled reaction mixture was concentrated in vacuo, 100 ml of water were added, and the aqueous phase was extracted with ethyl acetate (4×60 ml). The combined organic phases were washed with saturated aqueous NaHCO3 solution, dried over magnesium sulfate and concentrated in vacuo. The residue was purified by chromatography on silica gel (mobile phase gradient 0-5% methanol in dichloromethane). Yield: 6.99 g (75%) of yellow solid
