Participants

Reaction Steps

3-(4-Chloro-2-nitroanilino)-2,5-dihydrothiophene-4-nitrile (14.09 g, 0.05 mol) dissolved in xylene (150 ml) was added to a solution of chloranil (12.3 g, 0.05 mol) in hot xylene (100 ml). The mixture was allowed to reflux for 2 hours. After cooling, the xylene was evaporated off under vacuum to leave a red-brown solid which was triturated with methanol to give a brick-red solid. The solid was recrystallised from hot methanol to give red crystals which were filtered off, washed with methanol and dried at 50° C. under vacuum. The dried product so obtained was the title compound, m.p. 214° C.
