実験手順
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 two 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.
