실험 절차
1-Amino-2-benzyloxymethyl-1-phthalimido-ethane (3.0 g, 9.7 mmol) is dissolved in 50 ml dry methanol and hydrazine hydrate (968 mg, 19.3 mmol) is added. After being refluxed for 4 hours, the reaction mixture is stirred for 24 hours at ambient temperature and 50 ml 2N hydrochloric acid was added. The phthalhydrazide is removed by filtration and the 1,2-diamino-1-benzyloxymethyl-ethane-dihydrochloride is purified by recrystallisation from dry ethanol.
