Reaction Steps

N1-(pyrid-3-yl)-4-methoxy-8-nitro-dibenzo[b,d]furan-1-carboxamide (500 mg) (from step 1) was reduced using raney nickel (150 mg) (30% w/w aqueous suspension) in methanol (10 ml) in the presence of hydrazine hydrate (0.32 ml) under gentle reflux for 4 h. The reaction mixture was flitered through celite and the filterate was concentrated in vaccuo. The residue was triturated with water, to obtain a solid which was filtered dried to give the product as white solid (300 mg).
