Versuchsvorschrift

To a cooled (water bath), stirred mixture of 2.42 g n-butylhydrazine hydrochloride in 15 mL tetrahydrofuran was added 1.7 g powdered potassium hydroxide. The resulting mixture was stirred and maintained under a nitrogen atmosphere as n-butyl isocyanate (1.49 g, 0.015 moles) in 30 mL tetrahydrofuran was added dropwise. After addition, the solution was stirred overnight at ambient temperature. Work up as in Example 5 above yielded 1.5 g N,1-dibutylhydrazinecarboxamide b.p. 135°-6° C. at 0.08 torr, m.p. 34°-36° C. This structure was confirmed by NMR analysis.
