実験手順
DCC (1.03 g, 4.97 mmol) was dissolved in tetrahydrofuran (15 mL). Hydrazine (135 mg, 4.22 mmol) was added via syringe. Stirring 30 hours at room temperature produced a clear yellow mixture which was evaporated to a white powder (922 mg). Solution of this powder in diethyl ether, filtration and acidification with HCl (60 mL of saturated Et2O) gave a yellow white precipitate (856 mg). Two recrystallizations (EtOH in an Et2O chamber) gave white prisms (133 mg, 18%, M.P. 288°-290° C.). The low percentage of nitrogen in the elemental analysis of this compound indicates that two equivalents of DCC have reacted to hydrazine, forming the title compound.
