実験手順

To a solution of 1-(hydroxymethyl)-4-propyl-pyrrolidin-2-one a24 (4 g, 25.44 mmol) and triethylamine (1.2 eq, 30.53 mmol, 3.089 g; 4.26 ml) in 25 ml of dichloromethane was added dropwise a solution of diethylcarbamyl choride (1.1 eq, 27.99 mmol, 3.795 g, 3.55 ml) in dichloromethane (5 ml) at room temperature. The crude mixture was allowed to react under agitation and inert atmosphere overnight. Hydrolysis (15 ml of water), extraction (CH2Cl2), drying of the combinated organic layers (MgSO4), filtration and solvent evaporation under reduced pressure gave (2-oxo-4-propylpyrrolidin-1-yl)methyl diethylcarbamate a26 (100%) which was used without any further purification.
