Reaction Steps
α-Aminoacetophenone hydrochloride (6.87 g, 0.040 mol) was mixed with 1-nitro-2-methylthio-2-methylsulphinylethylene (7.25 g, 0.040 mol) in 300 ml dry methanol and warmed at 60°. Sodium methoxide (from 0.92 g sodium, 0.080 g atom) in methanol (25 ml) was added dropwise, with stirring, over about 10 minutes. After addition, the mixture was stirred at 60° for one hour, and then filtered to give 2-methylthio-3-nitro-4-phenylpyrrole 5.66 g, m.p. 259°-261° dec.
