p-Chlorothiophenol → 1-[(4-Chlorophenyl)thio]-1-[(4-methoxyphenyl)hydrazono]-2-propanone

Participants

Reaction Steps

A suspension of 31.7 g (0.139 mol) of 1-chloro-1-[(4-methoxyphenyl)hydrazono]-2-propanone in 400 ml of ethanol was treated with 23.4 g (0.161 mole) of 4-chlorothiophenol followed by 23.4 ml of triethylamine. The suspension was heated at reflux for 2 hours and cooled. The resultant suspension was filtered and the precipitate was washed with 1 portion of cold ethanol. The solids were dried in vacuo to yield 35.77 g of 1-[(4-chlorophenyl)thio]-1-[(4-methoxyphenyl)hydrazono]-2-propanone, mp 111.5°-113.5° C.
