実験手順

A solution of the TFA salt of benzyl (2S,3S)-2-(2-aminoacetamido)-3-hydroxyhexyl(isobutyl)carbamate in 1:1 CH2Cl2/DMF was charged successively with N,N-diisopropylethylamine (0.139 mL), 3-nitro-5-trifluoromethylbenzoic acid (39 mg), and HATU (90 mg). The reaction was stirred for 14 h at RT before being partitioned between EtOAc and water. The organic phase was washed with sat. NH4Cl, water, and brine before being dried (Na2SO4), filtered, and concentrated in vacuo to afford benzyl (2S,3S)-3-hydroxy-2-(2-(3-nitro-5-(trifluoromethyl)benzamido)acetamido)hexyl(isobutyl)carbamate (94 mg), which was taken onto the next step without further purification. MS found: (M+H)+=597.2.
