Abstract: N-methyl-2-pyrrolealdehyde was synthesized by the reaction of N-methylpyrrole with Vilsmerier reagent and by hydrolysis in Na_2CO_3 solution subsequently. Owing to Na_2CO_3 and dichloroethane instead of CH_3COONa and ether, the reformative process has effective solvent recovery and high security. After then, N-methyl-2-pyrrolecarbonitrile(MPC) was synthesized by oximation and dehydration of N-methyl-2-pyrrolealdehyde in hydroxylamined hydrochloride and acetic anhydride respectively. By neutralization of rea...
