실험 절차

To a mixture of 4-(tert-butoxycarbonylamino)-2-nitrobenzoic acid in 60 ml of dichloromethane were added 4.8 g of N,N,N′,N′-tetramethyl-O-(1H-benzotriazol-1-yl)-uronium-hexafluorophosphate. After stirring for 15 min. a mixture of 3.8 g of L-glutamic acid-di tert.-butylester hydrochloride in 60 ml dichloromethane and 3 ml triethylamine was added dropwise. After stirring for 20 hours at room temperature, the mixture was filtered and the filtrate was washed five times with 10% aqueous citric acid, four times with 5% aqueous sodium carbonate solution and two times with water. The organic layer was dried over magnesium sulphate and concentrated in vacuum to give 6.3 g of di-tert-butyl N-(4-(tert-butoxycarbonylamino)-2-nitrobenzamido)-L-glutamate as a yellow foam. This was directly used in example 3.
