Participants

Reaction Steps

187 mg of (±)-cis-3-ethyl-4-hydroxymethyl-2-azetidinone, 300 mg of imidazole, and 300 mg of t-butyldimethylsilyl chloride in 3 ml dry dimethylformamide (DMF) were stirred at room temperature for 2 hours. The mixture was concentrated to dryness and 25 ml of H2O:EtOAc (2:3) were added. The mixture was washed 3 times with 3 ml of H2O to remove DMF and imidazole and then dried over Na2SO4 and concentrated to yield the titled compound as white crystals. NMR (CDCl3): δ0.06 (6H, s), 0.89 (9H, s), 1.06 (3H, t), 1.48-1.88 (2H, m), 3.14 (1H, m), 3.56-3.90 (3H, m), 5.86 (1H, brs).
