実験手順
A solution of 23 g of ethyl dodecanoate and 62.7 g of ethylenediamine in 100 ml of tetrahydrofuran (THF) was refluxed for 3 hours and the excess THF was distilled off. The reaction mixture was heated at 100° C. for 16 hours, cooled to room temperature, poured into cold water and extracted with ether. After drying, the organic solution was concentrated to give 15.7 g of crude product and this was recrystallized from ether-hexane to give 10.9 g of pure product, m.p. 64°-66° C.
