実験手順

A 1 L round bottom flask was charged with 4-nitrobenzene-1,2-diamine (40 g, 0.26 mol), methyl iodide (13 ml, 0.21 mol) and DMF (300 ml), followed by the addition of saturated sodium carbonate (60 ml) over 2-3 minutes under rapid stirring. After stirring overnight at room temperature the reaction mixture was filtered and then concentrated in vacuo to a dark red oil. The residue was purified by flash column chromatography (15 to 30% ethyl acetate/petrol) to afford the title compound (27 g, 61% yield).
