2-Imidazolidinone → HCID 68700715, compound

Participants

Reaction Steps

To a solution of imidazolidin-2-one (0.2 g; 2.3 mmol) in anhydrous DMF (5 ml) 60% NaH in mineral oil (0.18 g; 4.6 mmol) was added at room temperature, under N2. After stirring for 1 h, tert-butyl 2-bromoacetate (0.35 ml; 2.3 mmol) was added. The resulting mixture was stirred for additional 2 h and solvents were removed in vacuo. The residue was diluted to 15 ml with EtOAc, washed with H2O, brine, dried over anhydrous MgSO4 and filtered. The filtrate was evaporated under reduced pressure and the residue was purified by FCC (SiO2, EtOAc) to give the title compound (0.12 g; 26%) as a colourless solid. 1H-NMR (CDCl3) 4.61 (broad s, 1H); 3.83 (s, 2H); 3.58-3.41 (m, 4H); 1.44 (s, 9H).
