실험 절차

3.10 g (30.96 mmol) N-hydroxy-cyclopropanecarboxamidine are placed in 10 ml dimethylformamide and molecular sieve. 1.32 g (34.06 mmol) sodium hydride (60% in mineral oil) are added. The mixture is stirred for 0.1 hours at 50° C., then 7.40 g (34.06 mmol) ethyl 3-tert-butoxycarbonylamino-propionate in 20 ml dimethylformamide are added. The reaction mixture is stirred for 3 hours at 50° C. After cooling 15 ml of water are added, the mixture is suction filtered through Celite. The 2 phases of the filtrate are separated, the aqueous phase is extracted with ethyl acetate, the combined organic phase is evaporated down. The residue is purified by chromatography.
