実験手順

Acetic acid 3-acetoxy-2-tert-butoxycarbonylamino-propyl ester (7.2 g) was dissolved in trifluoroacetic acid (40 ml) and stirred at ambient temperature. Effervescence was rapid at the start and had stopped after 1 h when the volatiles were removed at reduced pressure to give the product as a viscous oil in quantitative yield.
