반응 단계
A mixture of methyl 3,4-diamino-2-methylthiophene-5-carboxylate (1.0 g) and N,N'-thiocarbonyldiimidazole (1.1 g) in DMF (5 ml) was stirred at 50° C. for one hour. To the reaction mixture was added water to give crystals. Recrystallization from DMF-water afforded colorless prisms (1.2 g, quantitatively), m.p. 285°-288° C. (dec.)
