Reaction Steps

The mixture of 2.83 g of N-(4-nitro-o-tolyl)-pyridine-2,3-dicarboximide, 200 ml of ethyl acetate and 1.6 g of prewashed Raney nickel is hydrogenated at 3.1 atm. and room temperature until the hydrogen uptake ceases. It is filtered, evaporated, the residue taken up in chloroform, the solution treated with charcoal, filtered, evaporated and the residue recrystallized from methanol, to yield the N-(4-amino-o-tolyl)-pyridine-2,3-dicarboximide of the formula ##SPC6##
