実験手順
1.5 g (0.85 mmol) of ethyl 2-cyano-3-[(1,1-dioxido-2,3-dihydro-1-benzothien-5-yl)amino]acrylate were suspended in 15 ml of Dowtherm A and heated in a metal bath at 290° C. for about 1 h. The reaction mixture was then cooled to RT. The mixture was subsequently mixed with hexane and stirred at RT for 30 min; the precipitate produced thereby was filtered off with suction and washed with hexane. 836 mg (65%) of the desired product were obtained in the form of brownish crystals.
