Reaction Steps
A solution of 14.9g (0.137 mole) of 1-methylpyrrole-3-carboxaldehyde, 7.3 ml (0.137 mole) of nitromethane, 2.3 ml (.021 mole) of benzyl amine and 1.2 ml (.021 mole) of acetic acid in 20 ml of absolute ethanol is warmed briefly and stirred for 6 hours. It is then cooled and the precipitated solid is collected, giving as a yellow solid, 1-methyl-3-(2-nitrovinyl)pyrrole; m.p. 90°-92° C.
