Sodium Hydroxide → benzyl N-[(oxiran-2-yl)methyl]carbamate

Participants

Reaction Steps

A solution of allyl-carbamic acid benzyl ester (9.6 g, 50 mmol) in DCM (250 mL) was treated with mCPBA (11.55 g, 50 mmol, 75% purity) and the mixture was stirred at rt for 4 h. The pH of the mixture was adjusted to 9 by addition of 1M aq. NaOH. The phases were separated and the org. phase dried over MgSO4 and concentrated. The residue was purified by CC (hex/EA 2:1) to give the desired intermediate (7.4 g, 71% yield) as a colourless oil.
