Reaction Steps

To 84 g. (1.0 mole) of diketene contained in a three-necked round-bottom flask fitted with a mechanical stirrer addition funnel and reflux condenser and heated to 50° C. is added 500 mg. of sodium acetate followed by 175.2 g. (1.0 mole) of N-methyl-N-t-butyloxycarbonylethanolamine over a period of 20-30 minutes. The reaction mixture is allowed to stir at room temperature for 1 hour, after which it is distilled under reduced pressure to provide the desired product, 2-(N-methyl-N-t-butyloxycarbonylamino)ethyl acetoacetate.
