2-Chloro-3,5-dinitropyridine → N-(2H-1,3-Benzodioxol-5-yl)-3,5-dinitropyridin-2-amine

Participants

Reaction Steps

To a stirred solution of 12.0 g. (0.0875 mole) of 3,4-methylenedioxyaniline in 100 ml. of methanol, was added with stirring 8.0 g. (0.04 mole) of 2-chloro-3,5-dinitropyridine. Within one minute the mixture had crystallized. To complete the reaction, the mixture was heated on a steam bath for 15 minutes, then cooled and filtered to give 11.0 g. of product. A small amount recrystallized from methanol melted at 187°-188° C.
