Versuchsvorschrift

250 mg (3.01 mmol) of cyclopropyl isocyanate, dissolved in 3 ml THF, are added dropwise to 500 mg (3.01 mmol) of 2-methoxybenzoic acid hydrazide, dissolved in 7 ml THF, and the mixture stirred overnight at room temperature. The resulting precipitate is filtered off, washed with diethyl ether and dried in vacuo. 709 mg (94% of theory) of the target compound are thus obtained.
