실험 절차
To a solution of 1.15 g (0.05 mol) of sodium in 80 mL of absolute ethanol was added 4.5 mL of methyl cyanoacetate and 6.5 g (0.05 mol) of benzyl azide. A white precipitate formed immediately, and the resulting mixture was stirred overnight. The yellowish creamy mixture was poured into 500 mL of ice water, and a crude yellow precipitate was collected by filtration. Recrystallization from ethanol afforded the title compound as a pale yellow solid (5.0 g, 42%). m.p. 153° C.
