실험 절차

The synthesis was achieved in analogy to example 2 by using L-glutamic acid-dimethylester-hydrochloride instead of the L-glutamic acid-di-tert.-butylester-hydrochloride. From 14.8 g of 4-(tert-butoxycarbonylamino)-2-nitrobenzoic acid 27.4 g of crude dimethyl-N-(4-(tert.-butoxycarbonylamino)-2-nitrobenzamido)-L-glutamate were obtained which were purified twice by flash chromatography using silicagel 60 and ethylacetate/n-heptane/65:35 as eluent. After purification 17.38 g of dimethyl-N-(4-(tert.-butoxycarbonylamino)-2-nitrobenzamido)-L-glutamate were obtained.
