Participants

Reaction Steps

The mixture of 1.55 g of N-(4-nitro-o-tolyl)-thiophene-2,3-dicarboximide, 0.7 g of Raney nickel and 180 ml of ethyl acetate is hydrogenated at 2.7 atm. and room temperature until the hydrogen uptake ceases. It is filtered, evaporated and the residue recrystallized from ethyl acetate-diethyl ether to yield the N-(4-amino-o-tolyl)-thiophene-2,3-dicarboximide melting at 237°-240°.
