反応手順

To a solution of ethyl 3,3,3-trifluoro-2-oxopropanoate (30 g, 176 mmol) in dichloromethane (1 L) was added benzyl carbamate (26.6 g). The reaction mixture was stirred at ambient temperature for 24 h and the resulting precipitate was collected by filtration and dried under vacuum to afford ethyl 2-(benzyloxycarbonylamino)-3,3,3-trifluoro-2-hydroxypropanoate (49.0 g, 87% yield), which was used directly without further purification.
