実験手順
To a solution of 1-(hydroxymethyl)-4-propylpyrrolidin-2-one x2 (4 g, 25.44 mmol) and triethylamine (1.2 eq, 30.53 mmol, 3.089 g, 4.26 ml) in CH2Cl2 (25 ml) is added dropwise a solution of diethylcarbamyl chloride (1.1 eq, 27.99 mmol, 3.795 g, 3.55 ml) in CH2Cl2 (5 ml) at room temperature. The reaction mixture is 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 gives (2-oxo-4-propylpyrrolidin-1-yl)methyl diethylcarbamate x6 (100%) which is used without any further purification.
