反応手順

Under an argon atmosphere, 4.00 g (23.4 mmol) of 4-chlorobenzoic acid hydrazide are placed in 50 ml tetrahydrofuran. 1.95 g (23.4 mmol) of cyclopropyl isocyanate, dissolved in 50 ml tetrahydrofuran, are added dropwise at 50° C., and the mixture further stirred overnight at 50° C. The solvent is evaporated in vacuo, diethyl ether is added to the residue and the solid formed is isolated and purified by filtration and further washing with diethyl ether. 5.92 g (ca. 100% of theory) of the target compound are thus obtained.
