Reaction Steps

An amount of 5.00 g (29.3 mmol) of 4-chlorobenzenecarbohydrazide was suspended in dry tetrahydrofuran (150 ml) at 50° C. and then 2.63 ml (29.9 mmol) of allyl isocyanate in solution in 110 ml of dry tetrahydrofuran were added dropwise. The starting material underwent temporary complete dissolution, and then a fine precipitate was produced. The mixture was stirred at 50° C. for 2 hours. After cooling to room temperature it was admixed with diethyl ether. The colourless solid was isolated by suction filtration, washed with diethyl ether and dried in a high vacuum. This gave 7.42 g (100% of theory) of the target compound.
