Diethyl Ether → 3,4-Dichlorobenzhydrazide

Participants

Reaction Steps

17.5g (0.08 mol) of 3,4-dichlorobenzoic ethyl ester and 4.3g (0.086 mol) of 100%-hydrazine hydrate in 30 ml of ethanol were refluxed under heat for 6.5 hours. Upon cooled, the sedimented white crystals were added with ethyl ether and the reaction mixture was enough agitated and pulverized. The thus resulted products were filtered and enough washed with ethyl ether to provide 9.3g of 3,4-dichlorobenzoic hydrazide in white crystals. m.p.: 168°-170° C. Yield: 57%.
